NAME
Math::BigInt::FastCalc - Math::BigInt::Calc with some XS for more speed
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';
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:
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';
The default behaviour is to chose the best internal representation of
big integers, but the base length used in the internal representation
can be specified explicitly. Note that this must be done before
Math::BigInt is loaded. For example,
use Math::BigInt::FastCalc base_len => 3;
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:
_is_odd _is_even _is_one _is_zero
_is_two _is_ten
_zero _one _two _ten
_acmp _len
_inc _dec
__strip_zeros _copy
