=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
|
||

|
|
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.
