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

BUGS ^
