=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 => 'FastCalc';

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

# to use it with Math::BigRat
    use Math::BigRat lib => '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<Math::BigInt::GMP> or L<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';

=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<http://bloodgate.com/>
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>pjacklam@online.noE<gt> 2010-2016.
