NAME

Math::Prime::Simple - calculate prime numbers.

SYNOPSIS

use Math::Prime::Simple q/:all/;

@ranges = (    [ 1000, 1100 ],
             [ 10000, 11000 ],
);

# primes calculation
$primes = prime (\@ranges);

# primes iteration
while ($prime = each_prime (0, $primes)) {
    print "$prime\n";
}

DESCRIPTION

Math::Prime::Simple calculates prime numbers by applying the Sieve of Eratosthenes.

FUNCTIONS

prime

Calculates prime numbers.

@ranges = (   [ 1000, 1100 ],
            [ 10000, 11000 ],
);

$primes = prime (\@ranges);

Each range within @ranges will be evaluated and its prime numbers will be saved within the array ref $primes, accessible by the array index e.g the prime numbers of the first range may be accessed by @{$$primes[0]}.

each_prime

Returns each prime number in a scalar context.

while ($prime = each_prime ($item, $primes)) {
    print "$prime\n";
}

$item equals the array index of @ranges.

If not all prime numbers are being evaluated by each_prime(), it is recommended to undef @{"Math::Prime::Simple::each_prime_$item"} after usage of each_prime().

EXPORT

prime(), each_prime() upon request.
