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';

       The default behaviour is to chose the best internal representation of big integers, but the base length
       used in the internal representation can be specified explicitly. Note that this must be done before
       Math::BigInt is loaded.  For example,

           use Math::BigInt::FastCalc base_len => 3;
           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
