* Fix CPAN RT #130736 regarding numify() on a Math::BigFloat with a large number of digits and an equally large, but negative, exponent. * Fix a problem in to_ieee754() due to rounding in bpow(). 1.999817 2019-10-11 * Avoid non-integers in intermediate computations in Math::BigInt::Calc. This causes errors due to rounding issues, e.g., 47265625999999999 / 1000000000 is 47265626 with double precision. * Remove api_version() and the corresponding test file. There is no need to check which methods are supported by a backend library now that each backend library is a subclass of Math::BigInt::Lib. Methods not provided in the backend library are provided by the parent class. * Add to_ieee745() and from_ieee754(). * Add backermann() and ackermann() for the Ackermann function. * Add buparrow() and uparrow() for Knuth's up-arrow notation. * Add information about the github repository. * Update links in SUPPORT section in POD. * Fix bpow(). It returned NaN when it should truncate to zero. * Make blsft() in Math::BigInt allow bases up until the largest unsigned integer. * Make _lsft() in Math::BigInt::Calc handle an arbitrarily large base. * Add new methods bdigitsum() and digitsum() to Math::BigInt. Add new method _digitsum() to Math::BigInt::Lib. * Add new methods is_non_negative() and is_non_positive(). * Extend the default collation sequence used by to_base() and from_base() to all the 94 printable ASCII characters except blank/space. * Make new() in Math::BigFloat handle octal floating point numbers. * Slightly more robust t/01load.t. * Remove unused variables. * Miscellaneous code cleanup. |
