Not intended to be used by other modules. Other modules which sport the same functions can also be used to support Math::BigInt, like Math::BigInt::GMP or Math::BigInt::Pari. .PP In order to allow for multiple big integer libraries, Math::BigInt was rewritten to use library modules for core math routines. Any module which follows the same API as this can be used instead by using the following: .PP .Vb 1 \& use Math::BigInt lib => \*(Aqlibname\*(Aq; .Ve .PP \&'libname' is either the long name ('Math::BigInt::Pari'), or only the short version like 'Pari'. To use this library: .PP .Vb 1 \& use Math::BigInt lib => \*(AqFastCalc\*(Aq; .Ve .PP The default behaviour is to chose the best internal representation of big integers, but the base length used in the internal representation can be specified explicitly. Note that this must be done before Math::BigInt is loaded. For example, .PP .Vb 2 \& use Math::BigInt::FastCalc base_len => 3; \& use Math::BigInt lib => \*(AqFastCalc\*(Aq; .Ve .SH STORAGE .IX Header "STORAGE" Math::BigInt::FastCalc works exactly like Math::BigInt::Calc. Numbers are stored in decimal form chopped into parts. .SH METHODS .IX Header "METHODS" The following functions are now implemented in FastCalc.xs: .PP .Vb 6 \& _is_odd _is_even _is_one _is_zero \& _is_two _is_ten \& _zero _one _two _ten \& _acmp _len \& _inc _dec \& _\|_strip_zeros _copy .Ve .SH BUGS .IX Header "BUGS" Please report any bugs or feature requests to \&\f(CW\*(C`bug\-math\-bigint\-fastcalc at rt.cpan.org\*(C'\fR, or through the web interface at <https://rt.cpan.org/Ticket/Create.html?Queue=Math\-BigInt\-FastCalc> (requires login). We will be notified, and then you'll automatically be notified of progress on your bug as I make changes. .SH SUPPORT .IX Header "SUPPORT" After installing, you can find documentation for this module with the perldoc command. .PP .Vb 1 \& perldoc Math::BigInt::FastCalc .Ve .PP You can also look for information at: .IP GitHub 4 .IX Item "GitHub" <https://github.com/pjacklam/p5\-Math\-BigInt\-FastCalc> .IP "RT: CPAN's request tracker" 4 .IX Item "RT: CPAN's request tracker" <https://rt.cpan.org/Dist/Display.html?Name=Math\-BigInt\-FastCalc> .IP MetaCPAN 4 .IX Item "MetaCPAN" <https://metacpan.org/release/Math\-BigInt\-FastCalc> .IP "CPAN Testers Matrix" 4 .IX Item "CPAN Testers Matrix" <http://matrix.cpantesters.org/?dist=Math\-BigInt\-FastCalc> .IP "CPAN Ratings" 4 .IX Item "CPAN Ratings" <https://cpanratings.perl.org/dist/Math\-BigInt\-FastCalc> .SH LICENSE .IX Header "LICENSE" This program is free software; you may redistribute it and/or modify it under the same terms as Perl itself. .SH AUTHORS .IX Header "AUTHORS" Original math code by Mark Biggar, rewritten by Tels <http://bloodgate.com/> in late 2000. .PP Separated from Math::BigInt and shaped API with the help of John Peacock. .PP Fixed, sped-up and enhanced by Tels http://bloodgate.com 2001\-2003. Further streamlining (api_version 1 etc.) by Tels 2004\-2007. .PP Maintained by Peter John Acklam <pjacklam@gmail.com> 2010\-2021. .SH "SEE ALSO" .IX Header "SEE ALSO" Math::BigInt::Lib for a description of the API. .PP Alternative libraries Math::BigInt::Calc, Math::BigInt::GMP, and Math::BigInt::Pari. .PP Some of the modules that use these libraries Math::BigInt, Math::BigFloat, and Math::BigRat.
