this should work:


// couple of includes you need
#include <stdlib.h>
#include <time.h>


// the random number code
srand( (unsigned)time( NULL ) );

float randomnum = (float)rand() / (float)RAND_MAX; // RAND_MAX = 32767

// now use randomnum however you like


That's really all there is to it. rand() returns an integer between 0 and RAND_MAX (which is 32767) so you can get pretty much any kind of random number from it.
