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 \s-1API\s0 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 .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 (requires login).
