true 6 random numbers...

[perlone]

I don't know that much about creating a true random numbers. I want to make 6 random numbers like 125758. Anybody knows how? I use the following but it gives me one of those nonsense numebers:

$random_numbers = srand(6);

That gives you like: 2.99826324451715. Which is not a good help. Anybody knows?

Aaron,

Have another look at the documentation for srand, I don't think it's doing quite what you want it to:

[tt]perldoc -f srand[/tt]

There is a module called Math::TruelyRandom I believe that you can download from CPAN and it does a pretty good job at creating a truely random number.

Hope this helps,

Since rand returns a random value between 0 and 1, you can just multiply the result by 1000000 and take the integer value of that:

$rnum = int(rand * 1000000);

Note that since this may give numbers with leading zeroes, you should probably check the size:

$rnum = 0;
while ( $rnum < 99999 ) {
   $rnum = int(rand() * 1000000);
}

I just tested the above and it works fine.
