Math::BigInt::FastCalc

NAME

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

SYNOPSIS

  1.     # to use it with Math::BigInt
  2.     use Math::BigInt lib => 'FastCalc';
  4.     # to use it with Math::BigFloat
  5.     use Math::BigFloat lib => 'FastCalc';
  7.     # to use it with Math::BigRat
  8.     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:

  1. 	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:

  1. 	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:

  1. 	_is_odd		_is_even	_is_one		_is_zero
  2. 	_is_two		_is_ten
  3. 	_zero		_one		_two		_ten
  4. 	_acmp		_len
  5. 	_inc		_dec
  6. 	__strip_zeros	_copy
