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

-
Find the nth prime. if
n
= 0 finds the 1st prime >=start
, ifn
> 0 finds the nth prime >start
, ifn
< 0 finds the nth prime <start
