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


           # 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';


       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

       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

               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';


       Math::BigInt::FastCalc works exactly like Math::BigInt::Calc. Numbers
       are stored in decimal form chopped into parts.


       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
       <> in late 2000.  Separated from BigInt and shaped
       API with the help of John Peacock.

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

       Bug-fixing by Peter John Acklam <> 2010-2016.


       Math::BigInt::Lib(3) for a description of the API.

       Alternative libraries Math::BigInt::Calc(3), Math::BigInt::GMP(3),
       and Math::BigInt::Pari(3).

       Some of the modules that use these libraries Math::BigInt(3),
       Math::BigFloat(3), and Math::BigRat(3).
