This update restores support for suppression of the prompt with -P
when using the libedit or libreadline libraries for command line
editing and history.
This version adds support for command line editing and history using
the editline or readline libraries in addition to the line editing
features available in previous versions.
This version adds options and functions that allow to print numbers
in the open interval (-1 .. 1) with or without a leading 0 digit.
Additionally, an option has been added to prevent line wrap and
allows to print arbitrarily long results on a single line.
This is a new major release with a number of changes and extensions:
- Limited the number of temporary numbers and made the space for them
static so that allocating more space for them cannot fail.
- Allowed integers with non-zero scale to be used with power, places,
and shift operators.
- Added greatest common divisor and least common multiple to lib2.bc.
- Made bc and dc UTF-8 capable.
- Added the ability for users to have bc and dc quit on SIGINT.
- Added the ability for users to disable prompt and TTY mode by
environment variables.
- Added the ability for users to redefine keywords.
- Added dc's modular exponentiation and divmod to bc.
- Added the ability to assign strings to variables and array elements
and pass them to functions in bc.
- Added dc's asciify command and stream printing to bc.
- Added bitwise and, or, xor, left shift, right shift, reverse,
left rotate, right rotate, and mod functions to lib2.bc.
- Added the functions s2u(x) and s2un(x,n), to lib2.bc.
