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
_zero _one _two _ten
_acmp _len _num

Original math code by Mark Biggar, rewritten by Tels <http://bloodgate.com/>
in late 2000.
Seperated 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.
Math::BigInt::GMP, Math::BigInt::FastCalc and Math::BigInt::Pari.
