Math::BigInt::FastCalc3perl

Usage

    # 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';

Overview

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';

The default behaviour is to chose the best internal representation of big integers, but the base length used in the internal representation can be specified explicitly. Note that this must be done before Math::BigInt is loaded. For example,

    use Math::BigInt::FastCalc base_len => 3;
    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
