Changes
* The answer concerning Unicode support in the FAQ has been improved.
* The chapters in the manual that describe the types integer,
bigInteger, rational, bigRational and float have been improved.
* The function log10 has been added to the libraries integer.s7i and
bigint.s7i. This function computes the truncated base 10 logarithm.
* The operator sci has been added to the libraries integer.s7i,
bigInteger.s7i, bigrat.s7i and rational.s7i. This operator converts
a number to a string in scientific notation. Halfway cases are
rounded away from zero.
* The function round10 has been added to the libraries rational.s7i
and bigrat.s7i. It rounds halfway cases away from zero.
* The function str has been improved in the libraries rational.s7i
and bigrat.s7i. Now the function converts to a string with a
decimal representation (e.g.: "1.25"). When repeating decimals are
recognizend they are enclosed in parentheses.
* The operator digits has been improved in the libraries rational.s7i
and bigrat.s7i. Now the operator rounds halfway cases away from
zero.
* Documentation comments have been improved in bigint.s7i, float.s7i,
rational.s7i, bigrat.s7i, char.s7i, big_gmp.c and fltlib.c.
* Definitions of the constants integer.first and integer.last have
been added to integer.s7i.
* In bigrat.s7i and rational.s7i the function reduce has been
improved to accept Infinity and NaN.
* The function strDateTime has been added to time.s7i.
* A definition of INTTYPE_DECIMAL_SIZE has been added to s7c.sd7 and
common.h.
* The function bigGcd in big_rtl.c has been improved to make sure
that the greatest common divisor is positive or zero.
* Checks for log10, **, +:= and -:= have been added to chkbig.sd7.
* The checks for log2 have been improved and checks for log10 have
been added to chkint.sd7.
* Checks for the function str have been added to chkflt.sd7.
* The compiler has been improved to use the functions
bigIPowSignedDigit and bigGrowSignedDigit to optimize the operators
**, +:= and -:= for bigInteger operands.
* The compiler has been improved to support the actions INT_LOG10 and
BIG_LOG10.
* The function isPureFunction in the compiler has been improved.
* The functions bigGrowSignedDigit and bigLog10 have been added to
big_rtl.c and big_gmp.c.
* The program chkccomp.c has been improved to write definitions of
the macros isinf, DOUBLE_DECIMAL_EXPONENT_DIGITS, FLOAT_STR_FORMAT,
FLOAT_STR_LARGE_NUMBER, DOUBLE_STR_FORMAT, DOUBLE_STR_LARGE_NUMBER,
FLOAT_MANTISSA_FACTOR, FLOAT_MANTISSA_SHIFT, DOUBLE_MANTISSA_FACTOR
and DOUBLE_MANTISSA_SHIFT.
* The functions fltDgts and fltSci in flt_rtl.c have been changed to
raise RANGE_ERROR when the precision is negative.
* The function fltStri in flt_rtl.c has been improved to write a
reasonable number of fractional digits.
* The functions getMantissaAndExponent, setMantissaAndExponent and
doubleToCharBuffer have been added to flt_rtl.c.
* The function intLog10 has been added to int_rtl.c.
* The function stri_to_wstri has been renamed to stri_to_utf16.
* The functions stri_to_wstri_buf and wstri_buf_to_stri have been
added to striutl.c.
