Math::Prime::Util::GMP version 0.21

A set of utilities related to prime numbers.  These include multiple sieving
methods, primality tests, primality proving methods, prime counts using
Lehmer's method, nth_prime, approximations and bounds for the prime count
and nth prime, next_prime and prev_prime, moebius and totient functions,
integer factoring, and more.

These use GMP directly, so should be quite fast for bignums.  This module is
mainly intended to be used within Math::Prime::Util.


SYNOPSIS

  use bigint;
  use Math::Prime::Util::GMP qw/is_prime/;

  my $bignum = 27188762623694447842124996538064039444034480940561898523069471141322552613142248049662205275973369340310432664971214620312500867999795559094898390220747143052478910604268911012707898393728029267456459638286456542290811906119936040794792836567800517712998324001798156031927248728220625109007338679765933511619979774789836912923556217410691909195918721300495567162524824116421834972571058278049256235507898646245768556946276949788343519575161621940362646866507884693948582445313246609982609803440514973664475699712739781845803535392293307648102481184237357244142946254918813030632212409545324607906367812717102049454943;

  say "$bignum is ", is_prime($bignum) ? "prime" : "not prime";

methods included.


INSTALLATION

To install this module type the following:

   perl Makefile.PL
   make
   make test
   make install

You will need a C compiler compatible with the compiler used to build Perl,
and the GMP development system installed.  If you can install or have installed
Math::BigInt::GMP or Math::GMPz then this module should have no issues.

  Fedora:     sudo yum install gmp gmp-devel
  Ubuntu:     sudo apt-get install libgmp3 libgmp3-dev
  Cygwin:     install gmp, libgmp-devel, libgmp3


If you would like to make a standalone executable for ECPP, the easiest method
is to run the xt/create-standalone.sh script, which will create a standalone/
directory with Makefile and README.  You should make sure you have the large
discrimiment set (https://github.com/danaj/Math-Prime-Util-GMP/tree/master/xt/).
You may also simply compile it with:

  gcc -O3 -fomit-frame-pointer -DSTANDALONE -DSTANDALONE_ECPP ecpp.c bls75.c \
       ecm.c simpqs.c prime_iterator.c gmp_main.c small_factor.c utility.c \
       -lgmp -lm  -o ecpp-dj


DEPENDENCIES

Perl 5.6.2 or later.  No modules outside of Core have been used.
