| Summary : High speed arbitrary size integer math
|
Description :
Math::GMP was designed to be a drop-in replacement both for Math::BigInt
and for regular integer arithmetic. Unlike BigInt, though, Math::GMP uses
the GNU gmp library for all of its calculations, as opposed to straight
Perl functions. This can result in speed improvements.
The downside is that this module requires a C compiler to install -- a
small tradeoff in most cases. Also, this module is not 100% compatible with
Math::BigInt.
A Math::GMP object can be used just as a normal numeric scalar would be --
the module overloads most of the normal arithmetic operators to provide as
seamless an interface as possible. However, if you need a perfect
interface, you can do the following:
use Math::GMP qw(:constant);
$n = 2 ** (256 * 1024);
print \"n is $n\
\";
This would fail without the \':constant\' since Perl would use normal doubles
to compute the 250,000 bit number, and thereby overflow it into
meaninglessness (smaller exponents yield less accurate data due to floating
point rounding).
