NAME

Math::BigInt::FastCalc - Math::BigInt::Calc with some XS for more speed

SYNOPSIS

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 Math::BigInt::GMP or Math::BigInt::Pari.

DESCRIPTION

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 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';

Note that from Math::BigInt v1.76 onwards, FastCalc will be loaded automatically, if possible.

STORAGE

FastCalc works exactly like Calc, in stores the numbers in decimal form, chopped into parts.

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

Original math code by Mark Biggar, rewritten by Tels <bloodgate.com> in late 2000. Separated from BigInt and shaped with the help of John Peacock.

Fixed, sped-up and enhanced by Tels bloodgate.com 2001-2003. Further streamlining (api_version 1 etc.) by Tels 2004-2007.
