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
