NAME

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

SYNOPSIS

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.

DESCRIPTION

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.

STORAGE

FastCalc works exactly like Calc, in stores the numbers 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

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.
