I'm using the following code to generate a random Float number in XCode:

float randFloat = ((float)rand() / RAND_MAX) * 5.0 ;

The issue is that it's always give me the same number sequence even when I restart the simulator: -

0.000039 0.657689 3.778027 2.29351 etc.

Any idea how to fix this so that it generates random numbers every time?

Add `srand(time(NULL));` to start the seed. – Larme Nov 10 '14 at 19:15
Larme adding that now gives me values very close to each other and incrementing but not random. – thefan12345 Nov 10 '14 at 19:31
