Provides support for big integer calculations. Not intended to be used by other modules. Other modules which sport the same functions can also be used to support Math::BigInt, like L<Math::BigInt::GMP> or L<Math::BigInt::Pari>. 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: use Math::BigInt lib => 'libname'; 'libname' is either the long name ('Math::BigInt::Pari'), or only the short version like 'Pari'. To use this library: use Math::BigInt lib => 'FastCalc'; =head1 STORAGE Math::BigInt::FastCalc works exactly like Math::BigInt::Calc. Numbers are stored in decimal form chopped into parts. =head1 METHODS The following functions are now implemented in FastCalc.xs: _is_odd _is_even _is_one _is_zero _is_two _is_ten _zero _one _two _ten _acmp _len _inc _dec __strip_zeros _copy =head1 BUGS Please report any bugs or feature requests to C<bug-math-bigint-fastcalc at rt.cpan.org>, or through the web interface at L<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. =head1 SUPPORT You can find documentation for this module with the perldoc command. perldoc Math::BigInt::FastCalc You can also look for information at: =over 4 =item * RT: CPAN's request tracker L<https://rt.cpan.org/Public/Dist/Display.html?Name=Math-BigInt-FastCalc> =item * AnnoCPAN: Annotated CPAN documentation L<http://annocpan.org/dist/Math-BigInt-FastCalc> =item * CPAN Ratings L<http://cpanratings.perl.org/dist/Math-BigInt-FastCalc> =item * Search CPAN L<http://search.cpan.org/dist/Math-BigInt-FastCalc/> =item * CPAN Testers Matrix L<http://matrix.cpantesters.org/?dist=Math-BigInt-FastCalc> =item * The Bignum mailing list =over 4 =item * Post to mailing list C<bignum at lists.scsys.co.uk> =item * View mailing list L<http://lists.scsys.co.uk/pipermail/bignum/> =item * Subscribe/Unsubscribe L<http://lists.scsys.co.uk/cgi-bin/mailman/listinfo/bignum> =back =back =head1 LICENSE This program is free software; you may redistribute it and/or modify it under the same terms as Perl itself. =head1 AUTHORS Original math code by Mark Biggar, rewritten by Tels L<http://bloodgate.com/> in late 2000. Separated from BigInt and shaped API with the help of John Peacock. Fixed, sped-up and enhanced by Tels http://bloodgate.com 2001-2003. Further streamlining (api_version 1 etc.) by Tels 2004-2007. Bug-fixing by Peter John Acklam E<lt>pjacklam@online.noE<gt> 2010-2016. =head1 SEE ALSO L<Math::BigInt::Lib> for a description of the API. Alternative libraries L<Math::BigInt::Calc>, L<Math::BigInt::GMP>, and L<Math::BigInt::Pari>. Some of the modules that use these libraries L<Math::BigInt>, L<Math::BigFloat>, and L<Math::BigRat>. =cut
