C: rand
http://msdn.microsoft.com/library/default.asp?url=/library/en-
us/vclib/html/_CRT_rand.asp

and some small calculation like
double random()
{
return ((double) rand()) / (double) RAND_MAX;
}

Managed C++:

declare:
static rnd = new System.Random();

and use:
rnd.NextDouble();

See:

Do you need a memory-leak finder ?

#include <stdio.h

float number = rand() / (float) RAND_MAX

I think... didn't tried it :0)
