Import new 2-clause BSD licenced implementation of the bc and dc commands

These implementations of the bc and dc programs offer a number of advantages
compared to the current implementations in the FreeBSD base system:

- They do not depend on external large number functions (i.e. no dependency
  on OpenSSL or any other large number library)

- They implements all features found in GNU bc/dc (with the exception of
  the forking of sub-processes, which the author of this version considers
  as a security issue).

- They are significantly faster than the current code in base (more than
  2 orders of magnitude in some of my tests, e.g. for 12345^100000).

- They should be fully compatible with all features and the behavior of the
  current implementations in FreeBSD (not formally verified).

- They support POSIX message catalogs and come with localized messages in
  Chinese, Dutch, English, French, German, Japanese, Polish, Portugueze,
  and Russian.

- They offer very detailed man-pages that provide far more information than
  the current ones.

# News
## 3.0.2
This is a production release that adds `utf8` locale symlinks and removes an
unused `auto` variable from the `ceil()` function in the [extended math
library][16].
Users do ***NOT*** need to update unless they want the locales.
## 3.0.1
This is a production release with two small changes. Users do ***NOT*** need to
upgrade to this release; however, if they haven't upgraded to `3.0.0` yet, it
may be worthwhile to upgrade to this release.
The first change is fixing a compiler warning on FreeBSD with strict warnings
on.
The second change is to make the new implementation of `ceil()` in `lib2.bc`
much more efficient.
## 3.0.0
*Notes for package maintainers:*
*First, the `2.7.0` release series saw a change in the option parsing. This made
me change one error message and add a few others. The error message that was
changed removed one format specifier. This means that `printf()` will seqfault
on old locale files. Unfortunately, `bc` cannot use any locale files except the
global ones that are already installed, so it will use the previous ones while
running tests during install. **If `bc` segfaults while running arg tests when
updating, it is because the global locale files have not been replaced. Make
sure to either prevent the test suite from running on update or remove the old
locale files before updating.** Once this is done, `bc` should install without
problems.*
*Second, **the option to build without signal support has been removed**. See
below for the reasons why.*
This is a production release with some small bug fixes, a few improvements,
three major bug fixes, and a complete redesign of `bc`'s error and signal
handling. **Users and package maintainers should update to this version as soon
as possible.**
The first major bug fix was in how `bc` executed files. Previously, a whole file
was parsed before it was executed, but if a function is defined *after* code,
especially if the function definition was actually a redefinition, and the code
before the definition referred to the previous function, this `bc` would replace
the function before executing any code. The fix was to make sure that all code
that existed before a function definition was executed.
The second major bug fix was in `bc`'s `lib2.bc`. The `ceil()` function had a
bug where a `0` in the decimal place after the truncation position, caused it to
output the wrong numbers if there was any non-zero digit after.
The third major bug is that when passing parameters to functions, if an
expression included an array (not an array element) as a parameter, it was
accepted, when it should have been rejected. It is now correctly rejected.
Beyond that, this `bc` got several improvements that both sped it up, improved
the handling of signals, and improved the error handling.
First, the requirements for `bc` were pushed back to POSIX 2008. `bc` uses one
function, `strdup()`, which is not in POSIX 2001, and it is in the X/Open System
Interfaces group 2001. It is, however, in POSIX 2008, and since POSIX 2008 is
old enough to be supported anywhere that I care, that should be the requirement.
Second, the BcVm global variable was put into `bss`. This actually slightly
reduces the size of the executable from a massive code shrink, and it will stop
`bc` from allocating a large set of memory when `bc` starts.
Third, the default Karatsuba length was updated from 64 to 32 after making the
optimization changes below, since 32 is going to be better than 64 after the
changes.
Fourth, Spanish translations were added.
Fifth, the interpreter received a speedup to make performance on non-math-heavy
scripts more competitive with GNU `bc`. While improvements did, in fact, get it
much closer (see the [benchmarks][19]), it isn't quite there.
There were several things done to speed up the interpreter:
First, several small inefficiencies were removed. These inefficiencies included
calling the function `bc_vec_pop(v)` twice instead of calling
`bc_vec_npop(v, 2)`. They also included an extra function call for checking the
size of the stack and checking the size of the stack more than once on several
operations.
Second, since the current `bc` function is the one that stores constants and
strings, the program caches pointers to the current function's vectors of
constants and strings to prevent needing to grab the current function in order
to grab a constant or a string.
Third, `bc` tries to reuse `BcNum`'s (the internal representation of
arbitary-precision numbers). If a `BcNum` has the default capacity of
`BC_NUM_DEF_SIZE` (32 on 64-bit and 16 on 32-bit) when it is freed, it is added
to a list of available `BcNum`'s. And then, when a `BcNum` is allocated with a
capacity of `BC_NUM_DEF_SIZE` and any `BcNum`'s exist on the list of reusable
ones, one of those ones is grabbed instead.
In order to support these changes, the `BC_NUM_DEF_SIZE` was changed. It used to
be 16 bytes on all systems, but it was changed to more closely align with the
minimum allocation size on Linux, which is either 32 bytes (64-bit musl), 24
bytes (64-bit glibc), 16 bytes (32-bit musl), or 12 bytes (32-bit glibc). Since
these are the minimum allocation sizes, these are the sizes that would be
allocated anyway, making it worth it to just use the whole space, so the value
of `BC_NUM_DEF_SIZE` on 64-bit systems was changed to 32 bytes.
On top of that, at least on 64-bit, `BC_NUM_DEF_SIZE` supports numbers with
either 72 integer digits or 45 integer digits and 27 fractional digits. This
should be more than enough for most cases since `bc`'s default `scale` values
are 0 or 20, meaning that, by default, it has at most 20 fractional digits. And
45 integer digits are *a lot*; it's enough to calculate the amount of mass in
the Milky Way galaxy in kilograms. Also, 72 digits is enough to calculate the
diameter of the universe in Planck lengths.
(For 32-bit, these numbers are either 32 integer digits or 12 integer digits and
20 fractional digits. These are also quite big, and going much bigger on a
32-bit system seems a little pointless since 12 digits in just under a trillion
and 20 fractional digits is still enough for about any use since `10^-20` light
years is just under a millimeter.)
All of this together means that for ordinary uses, and even uses in scientific
work, the default number size will be all that is needed, which means that
nearly all, if not all, numbers will be reused, relieving pressure on the system
allocator.
I did several experiments to find the changes that had the most impact,
especially with regard to reusing `BcNum`'s. One was putting `BcNum`'s into
buckets according to their capacity in powers of 2 up to 512. That performed
worse than `bc` did in `2.7.2`. Another was putting any `BcNum` on the reuse
list that had a capacity of `BC_NUM_DEF_SIZE * 2` and reusing them for `BcNum`'s
that requested `BC_NUM_DEF_SIZE`. This did reduce the amount of time spent, but
it also spent a lot of time in the system allocator for an unknown reason. (When
using `strace`, a bunch more `brk` calls showed up.) Just reusing `BcNum`'s that
had exactly `BC_NUM_DEF_SIZE` capacity spent the smallest amount of time in both
user and system time. This makes sense, especially with the changes to make
`BC_NUM_DEF_SIZE` bigger on 64-bit systems, since the vast majority of numbers
will only ever use numbers with a size less than or equal to `BC_NUM_DEF_SIZE`.
Last of all, `bc`'s signal handling underwent a complete redesign. (This is the
reason that this version is `3.0.0` and not `2.8.0`.) The change was to move
from a polling approach to signal handling to an interrupt-based approach.
Previously, every single loop condition had a check for signals. I suspect that
this could be expensive when in tight loops.
Now, the signal handler just uses `longjmp()` (actually `siglongjmp()`) to start
an unwinding of the stack until it is stopped or the stack is unwound to
`main()`, which just returns. If `bc` is currently executing code that cannot be
safely interrupted (according to POSIX), then signals are "locked." The signal
handler checks if the lock is taken, and if it is, it just sets the status to
indicate that a signal arrived. Later, when the signal lock is released, the
status is checked to see if a signal came in. If so, the stack unwinding starts.
This design eliminates polling in favor of maintaining a stack of `jmp_buf`'s.
This has its own performance implications, but it gives better interaction. And
the cost of pushing and popping a `jmp_buf` in a function is paid at most twice.
Most functions do not pay that price, and most of the rest only pay it once.
(There are only some 3 functions in `bc` that push and pop a `jmp_buf` twice.)
As a side effect of this change, I had to eliminate the use of `stdio.h` in `bc`
because `stdio` does not play nice with signals and `longjmp()`. I implemented
custom I/O buffer code that takes a fraction of the size. This means that static
builds will be smaller, but non-static builds will be bigger, though they will
have less linking time.
This change is also good because my history implementation was already bypassing
`stdio` for good reasons, and unifying the architecture was a win.
Another reason for this change is that my `bc` should *always* behave correctly
in the presence of signals like `SIGINT`, `SIGTERM`, and `SIGQUIT`. With the
addition of my own I/O buffering, I needed to also make sure that the buffers
were correctly flushed even when such signals happened.
For this reason, I **removed the option to build without signal support**.
As a nice side effect of this change, the error handling code could be changed
to take advantage of the stack unwinding that signals used. This means that
signals and error handling use the same code paths, which means that the stack
unwinding is well-tested. (Errors are tested heavily in the test suite.)
It also means that functions do not need to return a status code that
***every*** caller needs to check. This eliminated over 100 branches that simply
checked return codes and then passed that return code up the stack if necessary.
The code bloat savings from this is at least 1700 bytes on `x86_64`, *before*
taking into account the extra code from removing `stdio.h`.
## 2.7.2
This is a production release with one major bug fix.
The `length()` built-in function can take either a number or an array. If it
takes an array, it returns the length of the array. Arrays can be passed by
reference. The bug is that the `length()` function would not properly
dereference arrays that were references. This is a bug that affects all users.
**ALL USERS SHOULD UPDATE `bc`**.
## 2.7.1
This is a production release with fixes for new locales and fixes for compiler
warnings on FreeBSD.
## 2.7.0
This is a production release with a bug fix for Linux, new translations, and new
features.
Bug fixes:
* Option parsing in `BC_ENV_ARGS` was broken on Linux in 2.6.1 because `glibc`'s
`getopt_long()` is broken. To get around that, and to support long options on
every platform, an adapted version of [`optparse`][17] was added. Now, `bc`
does not even use `getopt()`.
* Parsing `BC_ENV_ARGS` with quotes now works. It isn't the smartest, but it
does the job if there are spaces in file names.
The following new languages are supported:
* Dutch
* Polish
* Russian
* Japanes
* Simplified Chinese
All of these translations were generated using [DeepL][18], so improvements are
welcome.
There is only one new feature: **`bc` now has a built-in pseudo-random number
generator** (PRNG).
The PRNG is seeded, making it useful for applications where
`/dev/urandom` does not work because output needs to be reproducible. However,
it also uses `/dev/urandom` to seed itself by default, so it will start with a
good seed by default.
It also outputs 32 bits on 32-bit platforms and 64 bits on 64-bit platforms, far
better than the 15 bits of C's `rand()` and `bash`'s `$RANDOM`.
In addition, the PRNG can take a bound, and when it gets a bound, it
automatically adjusts to remove bias. It can also generate numbers of arbitrary
size. (As of the time of release, the largest pseudo-random number generated by
this `bc` was generated with a bound of `2^(2^20)`.)
***IMPORTANT: read the [`bc` manual][9] and the [`dc` manual][10] to find out
exactly what guarantees the PRNG provides. The underlying implementation is not
guaranteed to stay the same, but the guarantees that it provides are guaranteed
to stay the same regardless of the implementation.***
On top of that, four functions were added to `bc`'s [extended math library][16]
to make using the PRNG easier:
* `frand(p)`: Generates a number between `[0,1)` to `p` decimal places.
* `ifrand(i, p)`: Generates an integer with bound `i` and adds it to `frand(p)`.
* `srand(x)`: Randomizes the sign of `x`. In other words, it flips the sign of
`x` with probability `0.5`.
* `brand()`: Returns a random boolean value (either `0` or `1`).
## 2.6.1
This is a production release with a bug fix for FreeBSD.
The bug was that when `bc` was built without long options, it would give a fatal
error on every run. This was caused by a mishandling of `optind`.
## 2.6.0
This release is a production release ***with no bugfixes***. If you do not want
to upgrade, you don't have to.
No source code changed; the only thing that changed was `lib2.bc`.
This release adds one function to the [extended math library][16]: `p(x, y)`,
which calculates `x` to the power of `y`, whether or not `y` is an integer. (The
`^` operator can only accept integer powers.)
This release also includes a couple of small tweaks to the [extended math
library][16], mostly to fix returning numbers with too high of `scale`.
## 2.5.3
This release is a production release which addresses inconsistencies in the
Portuguese locales. No `bc` code was changed.
The issues were that the ISO files used different naming, and also that the
files that should have been symlinks were not. I did not catch that because
GitHub rendered them the exact same way.
## 2.5.2
This release is a production release.
No code was changed, but the build system was changed to allow `CFLAGS` to be
given to `CC`, like this:
```
CC="gcc -O3 -march=native" ./configure.sh
```
If this happens, the flags are automatically put into `CFLAGS`, and the compiler
is set appropriately. In the example above this means that `CC` will be "gcc"
and `CFLAGS` will be "-O3 -march=native".
This behavior was added to conform to GNU autotools practices.
## 2.5.1
This is a production release which addresses portability concerns discovered
in the `bc` build system. No `bc` code was changed.
* Support for Solaris SPARC and AIX were added.
* Minor documentations edits were performed.
* An option for `configure.sh` was added to disable long options if
`getopt_long()` is missing.
## 2.5.0
This is a production release with new translations. No code changed.
The translations were contributed by [bugcrazy][15], and they are for
Portuguese, both Portugal and Brazil locales.
## 2.4.0
This is a production release primarily aimed at improving `dc`.
* A couple of copy and paste errors in the [`dc` manual][10] were fixed.
* `dc` startup was optimized by making sure it didn't have to set up `bc`-only
things.
* The `bc` `&&` and `||` operators were made available to `dc` through the `M`
and `m` commands, respectively.
* `dc` macros were changed to be tail call-optimized.
The last item, tail call optimization, means that if the last thing in a macro
is a call to another macro, then the old macro is popped before executing the
new macro. This change was made to stop `dc` from consuming more and more memory
as macros are executed in a loop.
The `q` and `Q` commands still respect the "hidden" macros by way of recording
how many macros were removed by tail call optimization.
## 2.3.2
This is a production release meant to fix warnings in the Gentoo `ebuild` by
making it possible to disable binary stripping. Other users do *not* need to
upgrade.
## 2.3.1
This is a production release. It fixes a bug that caused `-1000000000 < -1` to
return `0`. This only happened with negative numbers and only if the value on
the left was more negative by a certain amount. That said, this bug *is* a bad
bug, and needs to be fixed.
**ALL USERS SHOULD UPDATE `bc`**.
## 2.3.0
This is a production release with changes to the build system.
## 2.2.0
This release is a production release. It only has new features and performance
improvements.
1. The performance of `sqrt(x)` was improved.
2. The new function `root(x, n)` was added to the extended math library to
calculate `n`th roots.
3. The new function `cbrt(x)` was added to the extended math library to
calculate cube roots.
## 2.1.3
This is a non-critical release; it just changes the build system, and in
non-breaking ways:
1. Linked locale files were changed to link to their sources with a relative
link.
2. A bug in `configure.sh` that caused long option parsing to fail under `bash`
was fixed.
## 2.1.2
This release is not a critical release.
1. A few codes were added to history.
2. Multiplication was optimized a bit more.
3. Addition and subtraction were both optimized a bit more.
## 2.1.1
This release contains a fix for the test suite made for Linux from Scratch: now
the test suite prints `pass` when a test is passed.
Other than that, there is no change in this release, so distros and other users
do not need to upgrade.
## 2.1.0
This release is a production release.
The following bugs were fixed:
1. A `dc` bug that caused stack mishandling was fixed.
2. A warning on OpenBSD was fixed.
3. Bugs in `ctrl+arrow` operations in history were fixed.
4. The ability to paste multiple lines in history was added.
5. A `bc` bug, mishandling of array arguments to functions, was fixed.
6. A crash caused by freeing the wrong pointer was fixed.
7. A `dc` bug where strings, in a rare case, were mishandled in parsing was
fixed.
In addition, the following changes were made:
1. Division was slightly optimized.
2. An option was added to the build to disable printing of prompts.
3. The special case of empty arguments is now handled. This is to prevent
errors in scripts that end up passing empty arguments.
4. A harmless bug was fixed. This bug was that, with the pop instructions
(mostly) removed (see below), `bc` would leave extra values on its stack for
`void` functions and in a few other cases. These extra items would not
affect anything put on the stack and would not cause any sort of crash or
even buggy behavior, but they would cause `bc` to take more memory than it
needed.
On top of the above changes, the following optimizations were added:
1. The need for pop instructions in `bc` was removed.
2. Extra tests on every iteration of the interpreter loop were removed.
3. Updating function and code pointers on every iteration of the interpreter
loop was changed to only updating them when necessary.
4. Extra assignments to pointers were removed.
Altogether, these changes sped up the interpreter by around 2x.
***NOTE***: This is the last release with new features because this `bc` is now
considered complete. From now on, only bug fixes and new translations will be
added to this `bc`.
## 2.0.3
This is a production, bug-fix release.
Two bugs were fixed in this release:
1. A rare and subtle signal handling bug was fixed.
2. A misbehavior on `0` to a negative power was fixed.
The last bug bears some mentioning.
When I originally wrote power, I did not thoroughly check its error cases;
instead, I had it check if the first number was `0` and then if so, just return
`0`. However, `0` to a negative power means that `1` will be divided by `0`,
which is an error.
I caught this, but only after I stopped being cocky. You see, sometime later, I
had noticed that GNU `bc` returned an error, correctly, but I thought it was
wrong simply because that's not what my `bc` did. I saw it again later and had a
double take. I checked for real, finally, and found out that my `bc` was wrong
all along.
That was bad on me. But the bug was easy to fix, so it is fixed now.
There are two other things in this release:
1. Subtraction was optimized by [Stefan Eßer][14].
2. Division was also optimized, also by Stefan Eßer.
## 2.0.2
This release contains a fix for a possible overflow in the signal handling. I
would be surprised if any users ran into it because it would only happen after 2
billion (`2^31-1`) `SIGINT`'s, but I saw it and had to fix it.
## 2.0.1
This release contains very few things that will apply to any users.
1. A slight bug in `dc`'s interactive mode was fixed.
2. A bug in the test suite that was only triggered on NetBSD was fixed.
3. **The `-P`/`--no-prompt` option** was added for users that do not want a
prompt.
4. A `make check` target was added as an alias for `make test`.
5. `dc` got its own read prompt: `?> `.
## 2.0.0
This release is a production release.
This release is also a little different from previous releases. From here on
out, I do not plan on adding any more features to this `bc`; I believe that it
is complete. However, there may be bug fix releases in the future, if I or any
others manage to find bugs.
This release has only a few new features:
1. `atan2(y, x)` was added to the extended math library as both `a2(y, x)` and
`atan2(y, x)`.
2. Locales were fixed.
3. A **POSIX shell-compatible script was added as an alternative to compiling
`gen/strgen.c`** on a host machine. More details about making the choice
between the two can be found by running `./configure.sh --help` or reading
the [build manual][13].
4. Multiplication was optimized by using **diagonal multiplication**, rather
than straight brute force.
5. The `locale_install.sh` script was fixed.
6. `dc` was given the ability to **use the environment variable
`DC_ENV_ARGS`**.
7. `dc` was also given the ability to **use the `-i` or `--interactive`**
options.
8. Printing the prompt was fixed so that it did not print when it shouldn't.
9. Signal handling was fixed.
10. **Handling of `SIGTERM` and `SIGQUIT`** was fixed.
11. The **built-in functions `maxibase()`, `maxobase()`, and `maxscale()`** (the
commands `T`, `U`, `V` in `dc`, respectively) were added to allow scripts to
query for the max allowable values of those globals.
12. Some incompatibilities with POSIX were fixed.
In addition, this release is `2.0.0` for a big reason: the internal format for
numbers changed. They used to be a `char` array. Now, they are an array of
larger integers, packing more decimal digits into each integer. This has
delivered ***HUGE*** performance improvements, especially for multiplication,
division, and power.
This `bc` should now be the fastest `bc` available, but I may be wrong.
## 1.2.8
This release contains a fix for a harmless bug (it is harmless in that it still
works, but it just copies extra data) in the [`locale_install.sh`][12] script.
## 1.2.7
This version contains fixes for the build on Arch Linux.
## 1.2.6
This release removes the use of `local` in shell scripts because it's not POSIX
shell-compatible, and also updates a man page that should have been updated a
long time ago but was missed.
## 1.2.5
This release contains some missing locale `*.msg` files.
## 1.2.4
This release contains a few bug fixes and new French translations.
## 1.2.3
This release contains a fix for a bug: use of uninitialized data. Such data was
only used when outputting an error message, but I am striving for perfection. As
Michelangelo said, "Trifles make perfection, and perfection is no trifle."
## 1.2.2
This release contains fixes for OpenBSD.
## 1.2.1
This release contains bug fixes for some rare bugs.
## 1.2.0
This is a production release.
There have been several changes since `1.1.0`:
1. The build system had some changes.
2. Locale support has been added. (Patches welcome for translations.)
3. **The ability to turn `ibase`, `obase`, and `scale` into stacks** was added
with the `-g` command-line option. (See the [`bc` manual][9] for more
details.)
4. Support for compiling on Mac OSX out of the box was added.
5. The extended math library got `t(x)`, `ceil(x)`, and some aliases.
6. The extended math library also got `r2d(x)` (for converting from radians to
degrees) and `d2r(x)` (for converting from degrees to radians). This is to
allow using degrees with the standard library.
7. Both calculators now accept numbers in **scientific notation**. See the
[`bc` manual][9] and the [`dc` manual][10] for details.
8. Both calculators can **output in either scientific or engineering
notation**. See the [`bc` manual][9] and the [`dc` manual][10] for details.
9. Some inefficiencies were removed.
10. Some bugs were fixed.
11. Some bugs in the extended library were fixed.
12. Some defects from [Coverity Scan][11] were fixed.
## 1.1.4
This release contains a fix to the build system that allows it to build on older
versions of `glibc`.
## 1.1.3
This release contains a fix for a bug in the test suite where `bc` tests and
`dc` tests could not be run in parallel.
## 1.1.2
This release has a fix for a history bug; the down arrow did not work.
## 1.1.1
This release fixes a bug in the `1.1.0` build system. The source is exactly the
same.
The bug that was fixed was a failure to install if no `EXECSUFFIX` was used.
## 1.1.0
This is a production release. However, many new features were added since `1.0`.
1. **The build system has been changed** to use a custom, POSIX
shell-compatible configure script ([`configure.sh`][6]) to generate a POSIX
make-compatible `Makefile`, which means that `bc` and `dc` now build out of
the box on any POSIX-compatible system.
2. Out-of-memory and output errors now cause the `bc` to report the error,
clean up, and die, rather than just reporting and trying to continue.
3. **Strings and constants are now garbage collected** when possible.
4. Signal handling and checking has been made more simple and more thorough.
5. `BcGlobals` was refactored into `BcVm` and `BcVm` was made global. Some
procedure names were changed to reflect its difference to everything else.
6. Addition got a speed improvement.
7. Some common code for addition and multiplication was refactored into its own
procedure.
8. A bug was removed where `dc` could have been selected, but the internal
`#define` that returned `true` for a query about `dc` would not have
returned `true`.
9. Useless calls to `bc_num_zero()` were removed.
10. **History support was added.** The history support is based off of a
[UTF-8 aware fork][7] of [`linenoise`][8], which has been customized with
`bc`'s own data structures and signal handling.
11. Generating C source from the math library now removes tabs from the library,
shrinking the size of the executable.
12. The math library was shrunk.
13. Error handling and reporting was improved.
14. Reallocations were reduced by giving access to the request size for each
operation.
15. **`abs()` (`b` command for `dc`) was added as a builtin.**
16. Both calculators were tested on FreeBSD.
17. Many obscure parse bugs were fixed.
18. Markdown and man page manuals were added, and the man pages are installed by
`make install`.
19. Executable size was reduced, though the added features probably made the
executable end up bigger.
20. **GNU-style array references were added as a supported feature.**
21. Allocations were reduced.
22. **New operators were added**: `$` (`$` for `dc`), `@` (`@` for `dc`), `@=`,
`<<` (`H` for `dc`), `<<=`, `>>` (`h` for `dc`), and `>>=`. See the
[`bc` manual][9] and the [`dc` manual][10] for more details.
23. **An extended math library was added.** This library contains code that
makes it so I can replace my desktop calculator with this `bc`. See the
[`bc` manual][3] for more details.
24. Support for all capital letters as numbers was added.
25. **Support for GNU-style void functions was added.**
26. A bug fix for improper handling of function parameters was added.
27. Precedence for the or (`||`) operator was changed to match GNU `bc`.
28. `dc` was given an explicit negation command.
29. `dc` was changed to be able to handle strings in arrays.
## 1.1 Release Candidate 3
This release is the eighth release candidate for 1.1, though it is the third
release candidate meant as a general release candidate. The new code has not
been tested as thoroughly as it should for release.
## 1.1 Release Candidate 2
This release is the seventh release candidate for 1.1, though it is the second
release candidate meant as a general release candidate. The new code has not
been tested as thoroughly as it should for release.
## 1.1 FreeBSD Beta 5
This release is the sixth release candidate for 1.1, though it is the fifth
release candidate meant specifically to test if `bc` works on FreeBSD. The new
code has not been tested as thoroughly as it should for release.
## 1.1 FreeBSD Beta 4
This release is the fifth release candidate for 1.1, though it is the fourth
release candidate meant specifically to test if `bc` works on FreeBSD. The new
code has not been tested as thoroughly as it should for release.
## 1.1 FreeBSD Beta 3
This release is the fourth release candidate for 1.1, though it is the third
release candidate meant specifically to test if `bc` works on FreeBSD. The new
code has not been tested as thoroughly as it should for release.
## 1.1 FreeBSD Beta 2
This release is the third release candidate for 1.1, though it is the second
release candidate meant specifically to test if `bc` works on FreeBSD. The new
code has not been tested as thoroughly as it should for release.
## 1.1 FreeBSD Beta 1
This release is the second release candidate for 1.1, though it is meant
specifically to test if `bc` works on FreeBSD. The new code has not been tested as
thoroughly as it should for release.
## 1.1 Release Candidate 1
This is the first release candidate for 1.1. The new code has not been tested as
thoroughly as it should for release.
## 1.0
This is the first non-beta release. `bc` is ready for production use.
As such, a lot has changed since 0.5.
1. `dc` has been added. It has been tested even more thoroughly than `bc` was
for `0.5`. It does not have the `!` command, and for security reasons, it
never will, so it is complete.
2. `bc` has been more thoroughly tested. An entire section of the test suite
(for both programs) has been added to test for errors.
3. A prompt (`>>> `) has been added for interactive mode, making it easier to
see inputs and outputs.
4. Interrupt handling has been improved, including elimination of race
conditions (as much as possible).
5. MinGW and [Windows Subsystem for Linux][1] support has been added (see
[xstatic][2] for binaries).
6. Memory leaks and errors have been eliminated (as far as ASan and Valgrind
can tell).
7. Crashes have been eliminated (as far as [afl][3] can tell).
8. Karatsuba multiplication was added (and thoroughly) tested, speeding up
multiplication and power by orders of magnitude.
9. Performance was further enhanced by using a "divmod" function to reduce
redundant divisions and by removing superfluous `memset()` calls.
10. To switch between Karatsuba and `O(n^2)` multiplication, the config variable
`BC_NUM_KARATSUBA_LEN` was added. It is set to a sane default, but the
optimal number can be found with [`karatsuba.py`][4] (requires Python 3)
and then configured through `make`.
11. The random math test generator script was changed to Python 3 and improved.
`bc` and `dc` have together been run through 30+ million random tests.
12. All known math bugs have been fixed, including out of control memory
allocations in `sine` and `cosine` (that was actually a parse bug), certain
cases of infinite loop on square root, and slight inaccuracies (as much as
possible; see the [README][5]) in transcendental functions.
13. Parsing has been fixed as much as possible.
14. Test coverage was improved to 94.8%. The only paths not covered are ones
that happen when `malloc()` or `realloc()` fails.
15. An extension to get the length of an array was added.
16. The boolean not (`!`) had its precedence change to match negation.
17. Data input was hardened.
18. `bc` was made fully compliant with POSIX when the `-s` flag is used or
`POSIXLY_CORRECT` is defined.
19. Error handling was improved.
20. `bc` now checks that files it is given are not directories.

## 1.0 Release Candidate 1
This is the first Release Candidate for 1.0. `bc` is complete, with `dc`, but it
is not tested.
## 0.5

# `bc`
[![Build Status][13]][14]
[![codecov][15]][16]
[![Coverity Scan Build Status][17]][18]
***WARNING: This project has moved to [https://git.yzena.com/][20] for [these
reasons][21], though GitHub will remain a mirror.***
This is an implementation of the [POSIX `bc` calculator][12] that implements
[GNU `bc`][1] extensions, as well as the period (`.`) extension for the BSD
flavor of `bc`.
For more information, see this `bc`'s [full manual][2].
This `bc` also includes an implementation of `dc` in the same binary, accessible
via a symbolic link, which implements all FreeBSD and GNU extensions. (If a
standalone `dc` binary is desired, `bc` can be copied and renamed to `dc`.) The
`!` command is omitted; I believe this poses security concerns and that such
functionality is unnecessary.
For more information, see the `dc`'s [full manual][3].
This `bc` is Free and Open Source Software (FOSS). It is offered under the BSD
2-clause License. Full license text may be found in the [`LICENSE.md`][4] file.
## Prerequisites
This `bc` only requires a C99-compatible compiler and a (mostly) POSIX
2008-compatible system with the XSI (X/Open System Interfaces) option group.
Since POSIX 2008 with XSI requires the existence of a C99 compiler as `c99`, any
POSIX and XSI-compatible system will have everything needed.
Systems that are known to work:
* Linux
* FreeBSD
* OpenBSD
* NetBSD
* Mac OSX
* Solaris
* AIX
Please submit bug reports if this `bc` does not build out of the box on any
system besides Windows. If Windows binaries are needed, they can be found at
[xstatic][6].
## Build
This `bc` should build unmodified on any POSIX-compliant system.
For more complex build requirements than the ones below, see the
[build manual][5].
### Pre-built Binaries
It is possible to download pre-compiled binaries for a wide list of platforms,
including Linux- and Windows-based systems, from [xstatic][6]. This link always
points to the latest release of `bc`.
### Default
For the default build with optimization, use the following commands in the root
directory:
```
./configure.sh -O3
make
```
### One Calculator
To only build `bc`, use the following commands:
```
./configure.sh --disable-dc
make
```
To only build `dc`, use the following commands:
```
./configure.sh --disable-bc
make
```
### Debug
For debug builds, use the following commands in the root directory:
```
./configure.sh -g
make
```
### Install
To install, use the following command:
```
make install
```
By default, `bc` and `dc` will be installed in `/usr/local`. For installing in
other locations, use the `PREFIX` environment variable when running
`configure.sh` or pass the `--prefix=<prefix>` option to `configure.sh`. See the
[build manual][5], or run `./configure.sh --help`, for more details.
### Package and Distro Maintainers
#### Recommended Compiler
When I ran benchmarks with my `bc` compiled under `clang`, it performed much
better than when compiled under `gcc`. I recommend compiling this `bc` with
`clang`.
I also recommend building this `bc` with C11 if you can because `bc` will detect
a C11 compiler and add `_Noreturn` to any relevant function(s).
#### Recommended Optimizations
I wrote this `bc` with Separation of Concerns, which means that there are many
small functions that could be inlined. However, they are often called across
file boundaries, and the default optimizer can only look at the current file,
which means that they are not inlined.
Thus, because of the way this `bc` is built, it will automatically be slower
than other `bc` implementations when running scripts with no math. (My `bc`'s
math is *much* faster, so any non-trivial script should run faster in my `bc`.)
Some, or all, of the difference can be made up with the right optimizations. The
optimizations I recommend are:
1. `-O3`
2. `-flto` (link-time optimization)
in that order.
Link-time optimization, in particular, speeds up the `bc` a lot. This is because
when link-time optimization is turned on, the optimizer can look across files
and inline *much* more heavily.
However, I recommend ***NOT*** using `-march=native`. Doing so will reduce this
`bc`'s performance, at least when building with link-time optimization. See the
[benchmarks][19] for more details.
#### Stripping Binaries
By default, non-debug binaries are stripped, but stripping can be disabled with
the `-T` option to `configure.sh`.
#### Using This `bc` as an Alternative
If this `bc` is packaged as an alternative to an already existing `bc` package,
it is possible to rename it in the build to prevent name collision. To prepend
to the name, just run the following:
```
EXECPREFIX=<some_prefix> ./configure.sh
```
To append to the name, just run the following:
```
EXECSUFFIX=<some_suffix> ./configure.sh
```
If a package maintainer wishes to add both a prefix and a suffix, that is
allowed.
**Note**: The suggested name (and package name) when `bc` is not available is
`bc-gh`.
#### Karatsuba Number
Package and distro maintainers have one tool at their disposal to build this
`bc` in the optimal configuration: `karatsuba.py`.
This script is not a compile-time or runtime prerequisite; it is for package and
distro maintainers to run once when a package is being created. It finds the
optimal Karatsuba number (see the [algorithms manual][7] for more information)
for the machine that it is running on.
The easiest way to run this script is with `make karatsuba`.
If desired, maintainers can also skip running this script because there is a
sane default for the Karatsuba number.
## Status
This `bc` is robust.
It is well-tested, fuzzed, and fully standards-compliant (though not certified)
with POSIX `bc`. The math has been tested with 40+ million random problems, so
it is as correct as I can make it.
This `bc` can be used as a drop-in replacement for any existing `bc`. This `bc`
is also compatible with MinGW toolchains, though history is not supported on
Windows.
In addition, this `bc` is considered complete; i.e., there will be no more
releases with additional features. However, it *is* actively maintained, so if
any bugs are found, they will be fixed in new releases. Also, additional
translations will also be added as they are provided.
## Comparison to GNU `bc`
This `bc` compares favorably to GNU `bc`.
* It has more extensions, which make this `bc` more useful for scripting.
* This `bc` is a bit more POSIX compliant.
* It has a much less buggy parser. The GNU `bc` will give parse errors for what
is actually valid `bc` code, or should be. For example, putting an `else` on
a new line after a brace can cause GNU `bc` to give a parse error.
* This `bc` has fewer crashes.
* GNU `bc` calculates the wrong number of significant digits for `length(x)`.
* GNU `bc` will sometimes print numbers incorrectly. For example, when running
it on the file `tests/bc/power.txt` in this repo, GNU `bc` gets all the right
answers, but it fails to wrap the numbers at the proper place when outputting
to a file.
* This `bc` is faster. (See [Performance](#performance).)
### Performance
Because this `bc` packs more than `1` decimal digit per hardware integer, this
`bc` is faster than GNU `bc` and can be *much* faster. Full benchmarks can be
found at [manuals/benchmarks.md][19].
There is one instance where this `bc` is slower: if scripts are light on math.
This is because this `bc`'s intepreter is slightly slower than GNU `bc`, but
that is because it is more robust. See the [benchmarks][19].
## Algorithms
To see what algorithms this `bc` uses, see the [algorithms manual][7].
## Locales
Currently, this `bc` only has support for English (and US English), French,
German, Portuguese, Dutch, Polish, Russian, Japanese, and Chinese locales.
Patches are welcome for translations; use the existing `*.msg` files in
`locales/` as a starting point.
In addition, patches for improvements are welcome; the last two messages in
Portuguese were made with Google Translate, and the Dutch, Polish, Russian,
Japanese, and Chinese locales were all generated with [DeepL][22].
The message files provided assume that locales apply to all regions where a
language is used, but this might not be true for, e.g., `fr_CA` and `fr_CH`.
Any corrections or a confirmation that the current texts are acceptable for
those regions would be appreciated, too.
## Other Projects
Other projects based on this bc are:
* [busybox `bc`][8]. The busybox maintainers have made their own changes, so any
bugs in the busybox `bc` should be reported to them.
* [toybox `bc`][9]. The maintainer has also made his own changes, so bugs in the
toybox `bc` should be reported there.
## Language
This `bc` is written in pure ISO C99, using POSIX 2008 APIs.
## Commit Messages
This `bc` uses the commit message guidelines laid out in [this blog post][10].
## Semantic Versioning
This `bc` uses [semantic versioning][11].

usage: %s [options] [file...]
bc is a command-line, arbitrary-precision calculator with a Turing-complete
language. For details, use `man %s`.
This bc is compatible with both the GNU bc and the POSIX bc spec. See the GNU bc
manual (https://www.gnu.org/software/bc/manual/bc.html) and bc spec
(http://pubs.opengroup.org/onlinepubs/9699919799/utilities/bc.html)
for details.
This bc has three differences to the GNU bc:
1) Arrays can be passed to the builtin "length" function to get the number of
elements currently in the array. The following example prints "1":
a[0] = 0
length(a[])
2) The precedence of the boolean "not" operator (!) is equal to that of the
unary minus (-), or negation, operator. This still allows POSIX-compliant
scripts to work while somewhat preserving expected behavior (versus C) and
making parsing easier.
3) This bc has many more extensions than the GNU bc does. For details, see the
man page.
Options:
-e expr --expression=expr
Run "expr" and quit. If multiple expressions or files (see below) are
given, they are all run before executing from stdin.
-f file --file=file
Run the bc code in "file" and exit. See above as well.
-g --global-stacks
Turn scale, ibase, and obase into stacks. This makes the value of each be
be restored on returning from functions. See the man page for more
details.
-h --help
Print this usage message and exit.
-i --interactive
Force interactive mode.
-l --mathlib
Use predefined math routines:
s(expr) = sine of expr in radians
c(expr) = cosine of expr in radians
a(expr) = arctangent of expr, returning radians
l(expr) = natural log of expr
e(expr) = raises e to the power of expr
j(n, x) = Bessel function of integer order n of x
-P --no-prompt
Disable the prompt in interactive mode.
-q --quiet
Don't print version and copyright.
-s --standard
Error if any non-POSIX extensions are used.
-w --warn
Warn if any non-POSIX extensions are used.
-v --version
Print version information and copyright and exit.

* The dc help text.
*
*/
usage: %s [options] [file...]
dc is a reverse-polish notation command-line calculator which supports unlimited
precision arithmetic. For details, use `man %s`.
This dc is (mostly) compatible with the FreeBSD dc and the GNU dc. See the
FreeBSD man page (https://www.unix.com/man-page/FreeBSD/1/dc/) and the GNU dc
manual (https://www.gnu.org/software/bc/manual/dc-1.05/html_mono/dc.html) for
details.
This dc has a few differences from the two above:
1) When printing a byte stream (command "P"), this bc follows what the FreeBSD
dc does.
2) This dc implements the GNU extensions for divmod ("~") and modular
exponentiation ("|").
3) This dc implements all FreeBSD extensions, except for "J" and "M".
4) This dc does not implement the run command ("!"), for security reasons.
5) Like the FreeBSD dc, this dc supports extended registers. However, they are
implemented differently. When it encounters whitespace where a register
should be, it skips the whitespace. If the character following is not
a lowercase letter, an error is issued. Otherwise, the register name is
parsed by the following regex:
[a-z][a-z0-9_]*
This generally means that register names will be surrounded by whitespace.
Examples:
l idx s temp L index S temp2 < do_thing
Also note that, unlike the FreeBSD dc, extended registers are not even
parsed unless the "-x" option is given. Instead, the space after a command
that requires a register name is taken as the register name.
Options:
-e expr --expression=expr
Run "expr" and quit. If multiple expressions or files (see below) are
given, they are all run. After running, dc will exit.
-f file --file=file
Run the dc code in "file" and exit. See above.
-h --help
Print this usage message and exit.
-i --interactive
Put dc into interactive mode. See the man page for more details.
-P --no-prompt
Disable the prompt in interactive mode.
-V --version
Print version and copyright and exit.
-x --extended-register
Enable extended register mode.
