1.15 2021-07-13
* This release does not add any new functionality. It is just to try to keep
the distribution up to date with the Perl environment.
* Make to_base() a front-end to Math::BigInt->to_base().
* Add to_base() to the list of exported functions.
* Make fibonacci() a front-end to Math::BigInt->bfac().
* Reorganize existing test files, and add more test files.
* Better Makefile.PL.
* The tests now require Test::More version 0.88 or newer.
* New MANIFEST.SKIP file based on the template in the ExtUtils-Manifest
distribution.
* Format CHANGES according to CPAN::Changes::Spec.
1.14 2016-12-03 pjacklam
* Remove BENCHMARK file. The information there was obsolete.
* Remove INSTALL file. The information is in the README file.
* Use ExtUtils::MakeMaker rather than Module::Install in Makefile.PL.
* Explicitly set required version of Math::BigInt in Math/Big.pm.
* Trim whitespace.
* Remove author information in LICENSE file.
* Update README file.
* Inform that the TODO file is not up to date.
1.13 2016-04-26 pjacklam
* Replace "use vars ..." with "our ...".
* Fix documentation error in Math::Big. (CPAN RT #60614)
* Add patch to speed up primes(). (CPAN RT #81986)
* Fix documentation error in Math::Big::Factors. (CPAN RT #100917)
* Use OO-style calls, e.g., Math::BigInt->bzero(), not Math::BigInt::bzero().
(CPAN RT #113959)
* Use "=pod" to start POD section.
* In the POD, replace "METHODS" header with "FUNCTIONS". OO-style calls are
not supported, so they are functions, not methods.
* In the POD, use "=item" for each function, not "=head2".
* Code reformatting.
* Remove trailing whitespace.
* Remove unnecessary "1;" at end of file.
* Add "use warnings" to all modules.
* In Makefile.PL, add "#!perl" to the top, as it gives nice syntax
highlighting in some editors.
* In Makefile.PL, update author information.
* In Makefile.PL, change required version of Math::BigInt to 1.82 (which
shipped with Math::BigFloat 1.54). This is the oldest version of
Math::BigInt (and Math::BigFloat) that work with this distribution.
* In Makefile.PL, change "build_requires 'Test::More' => 0.42" to
"test_requires 'Test::More' => 0.47". Test::More is only needed for testing,
not building, and version 0.47 is the required version.
* In Makefile.PL, change "require 5.6.2" to "require 5.006001". Math::BigInt
requires only Perl v5.6.1, not v5.6.2.
* Edit the "BUGS" file so it points to "rt.cpan.org".
* Edit the "NEW" file so it points to the "CHANGES" file.
* Remove stuff from POD that is covered in the more complete "CREDITS" file.
* Update the bundled version of Module::Install from v0.65 to v1.16.
* Add more entries to "MANIFEST.SKIP".
1.12 2007-04-17 Tels 182 tests
* speed up fibonacci():
+ by not making the argument a BigInt
+ caching a few more numbers
+ removing a few needless scalar computations
* fix bug in fibonacci() missing a few intermidiate results
* euler() just uses BigInt's fast bexp() method and is thus now MUHC faster
* require Math::BigInt v1.83 (and thus Perl v5.6.2)
* bundle and use Module::Install
##############################################################################
1.11 2005-01-02 Tels 177 tests
* streamlined euler()
* @k = hailstone() is about 3..4 times faster
* $k = scalar hailstone() is about 6..7 times faster
* primes() is about 1.5 times faster
* fix documentation for primes() (Thanx Es Allen Smith!)
* add to_base($n, $base, [$alphabet]) (Thanx Tilghman Lesher!)
1.10 2004-08-13 Tels 161 tests
* __END__ in Big.pm, remove shebang line
* removed needless return statements for more speed
* log() now simple calls BigFloat log for speed (it was unusable slow before)
* hailstone() is between two and three times faster
* pi() is slightly faster by caching two objects for '5' and '236'
* require Math::BigInt v1.72
* arctan(), tan(), sin(), cos() etc are now about 10% faster
* arcsin($x) were $x != 0 was broken
1.09 2003-12-11 Tels
* require Math::BigInt v1.67

* require BigInt v1.61
* some more tests
1.07 2002-27-03
