Math::BigInt::FastCalc - Math::BigInt::Calc with some XS for more speed
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';
Note that from Math::BigInt v1.76 onwards, FastCalc will be loaded automatically, if possible.
FastCalc works exactly like Calc, in stores the numbers 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 <[email protected]> 2010-2011.
