# NAME

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

# to use it with Math::BigInt use Math::BigInt lib => 'FastCalc'; # to use it with Math::BigFloat use Math::BigFloat lib => 'FastCalc'; # to use it with Math::BigRat use Math::BigRat lib => 'FastCalc';

# DESCRIPTION

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';

# STORAGE

Math::BigInt::FastCalc works exactly like Math::BigInt::Calc. Numbers are stored 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
