=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.
