# 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

# LICENSE

# AUTHORS

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> 2010-2011.
