Yes mr Obvious...

Jesper, it may be a good idea to have a link in your first post explaning what a prime number is. So people don't think it just shits out numbers...

This is a fairly old page so that number has probably been passed
Perfect number, Keik. Not prime. How the hell could 2^(anything) be a prime number, anyway? THINK.

Yeah, that or he misread it and thought perfect numbers and prime numbers are the same thing.

Not everyone have gone through it in school. Belive me I didn't. And I hadn't yet any usage of it yet... but I will soon. I'm going to program a encryption program in Java, and prime numbers are excellent for this.

Thought I did go and learn it myself in my free time.

And eh... what is the world record on this thing? Someone probably is having it shitting out very high prime numbers.

A little something on math in computers.

I wrote a program to print out part of the Fibonacci Series (1, 1, 2, 3, 5, 8, 13 ..). It does this for one second - starts from zero and just keeps adding. Here's the last number I got as input, wrapped to several rows:

26637621554905847147445327024884692677216120154526185436197037882845643156074699

63127820235074833946229486404312543803870603216914103527972905704641956818924173
57505052308527864375303364806192475684362384914297208276078316893839326854560802
04223109674406632518730277035738564502181303411468303865349856165762711836705254

That number has 475 digits!

Ofcourse, generating a prime is much slower since division is harder on the CPU than basic addition, but I think this proves my point anyway. Computers can do math insanely fast.

(Here's the source code of my program, adapted from another Wikipedia page. It's written in Perl.)
#! /usr/bin/perl

use bigint;

my ($a, $b) = (0, 1);
my $f = time;
for (;;) {
    if (time < $f + 2) {
      print("$a\n");
      ($a, $b) = ($b, $a+$b);
    } else { die; }
}

I'm so going to make a similar program... but in Java.

Yeah that program works quite well, it generated alot of prime numbers and very fast. Just then crash for some reason.

Yeah, it dies after one second. That's the purpose, to figure out how high it can go for one second. Again, that program did not generate primes exclusively, just numbers in the Fibonacci Series.
