=head1 NAME

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

=head1 SYNOPSIS

    # to use it with Math::BigInt
    use Math::BigInt lib =&gt; 'FastCalc';

    # to use it with Math::BigFloat
    use Math::BigFloat lib =&gt; 'FastCalc';

    # to use it with Math::BigRat
    use Math::BigRat lib =&gt; 'FastCalc';

=head1 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 L&lt;Math::BigInt::GMP&gt; or L&lt;Math::BigInt::Pari&gt;.

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 =&gt; '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 =&gt; 'FastCalc';

=head1 STORAGE

Math::BigInt::FastCalc works exactly like Math::BigInt::Calc. Numbers are
stored in decimal form chopped into parts.

=head1 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

=head1 AUTHORS

Original math code by Mark Biggar, rewritten by Tels L&lt;http://bloodgate.com/&gt;
in late 2000.
Separated from BigInt and shaped API with the help of John Peacock.

Fixed, sped-up and enhanced by Tels http://bloodgate.com 2001-2003.
Further streamlining (api_version 1 etc.) by Tels 2004-2007.

Bug-fixing by Peter John Acklam E&lt;lt&gt;pjacklam@online.noE&lt;gt&gt; 2010-2016.
