# The math/p5-Math-Prime-Util port

## p5-Math-Prime-Util-0.74 – utilities related to prime numbers, including fast sieves

## 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.
