%description
A module for number theory in Perl. This includes prime sieving, primality
tests, primality proofs, integer factoring, counts / bounds /
approximations for primes, nth primes, and twin primes, random prime
generation, and much more.

This module is the fastest on CPAN for almost all operations it supports.
This includes Math::Prime::XS, Math::Prime::FastSieve, Math::Factor::XS,
Math::Prime::TiedArray, Math::Big::Factors, Math::Factoring, and
Math::Primality (when the GMP module is available). For numbers in the
10-20 digit range, it is often orders of magnitude faster. Typically it is
faster than Math::Pari for 64-bit operations.

All operations support both Perl UV's (32-bit or 64-bit) and bignums. If
you want high performance with big numbers (larger than Perl's native
32-bit or 64-bit size), you should install Math::Prime::Util::GMP and
Math::BigInt::GMP. This will be a recurring theme throughout this
documentation -- while all bignum operations are supported in pure Perl,
most methods will be much slower than the C+GMP alternative.

The module is thread-safe and allows concurrency between Perl threads while
still sharing a prime cache. It is not itself multi-threaded. See the
Limitations section if you are using Win32 and threads in your program.
Also note that Math::Pari is not thread-safe (and will crash as soon as it
is loaded in threads), so if you use Math::BigInt::Pari rather than
Math::BigInt::GMP or the default backend, things will go pear-shaped.

Two scripts are also included and installed by default:

* primes.pl displays primes between start and end values or expressions, with
many options for filtering (e.g. twin, safe, circular, good, lucky, etc.).
Use '--help' to see all the options.

* factor.pl operates similar to the GNU 'factor' program. It supports bigint
and expression inputs.
