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
