**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
