NAME

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

SYNOPSIS

    # to use it with Math::BigInt
    use Math::BigInt lib => 'FastCalc';

    # to use it with Math::BigFloat
    use Math::BigFloat lib => 'FastCalc';

    # to use it with Math::BigRat
    use Math::BigRat lib => 'FastCalc';
 

DESCRIPTION

Math::BigInt::FastCalc inherits from Math::BigInt::Calc.

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.

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';
 

STORAGE

Math::BigInt::FastCalc works exactly like Math::BigInt::Calc. Numbers are stored 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

AUTHORS

Original math code by Mark Biggar, rewritten by Tels <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 <pjacklam@online.no> 2010-2016.
