NAME

Primesieve - Perl extension for primesieve

SYNOPSIS

use Primesieve;

@primes = generate_primes (0,1000);

DESCRIPTION

This modules gives you access to primesieve.

FUNCTIONS

@primes = generate_primes ($from, $to)

Returns a list of all primes in the specified range in list context. In scalar context an array-reference is returned.

generate_n_primes ($n, $start)

Returns a list of the first n primes >= start in list context. In scalar context an array-reference is retgurned.

$num = nth_prime ($n, $start)

Find the nth prime. if n = 0 finds the 1st prime >= start, if n > 0 finds the nth prime > start, if n < 0 finds the nth prime < start (backwards).

$num = count_primes ($start, $stop)

Counts primes within the given range.

$num = count_twins ($start, $stop)

Counts twin primes within the given range.

$num = count_triplets ($start, $stop)

Counts triple primes within the given range.

$num = count_quadruplets ($start, $stop)

Counts quadruplets primes within the given range.

$num = count_quintuplets ($start, $stop)

Counts quintuplets primes within the given range.

$num = count_sextuplets ($start, $stop)

Counts sextuplets primes within the given range.

$num = print_primes ($start, $stop)

Print primes within the given range to stdout.

$num = print_twins ($start, $stop)

Print twin primes within the given range to stdout.

$num = print_triplets ($start, $stop)

Print triple primes within the given range to stdout.

$num = print_quadruplets ($start, $stop)

$num = print_sextuplets ($start, $stop)

Print sextuplets primes within the given range to stdout.

$num = get_max_stop ()

Returns the largest valid stop number for primesieve.

$num = get_sieve_size ()
