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

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 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;

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 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.

Math::BigInt::Lib for a description of the API.

Alternative libraries Math::BigInt::Calc, Math::BigInt::GMP, and Math::BigInt::Pari.

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