Nice way to have random numbers [5,14] such as:
5 + arc4random() % 10

Thanks.

float initRan;
initRan = 5 + arc4random() % 16;
myRandomNumber = initRan / 10;

Check this: http://www.daniweb.com/forums/thread98545.html
or google for more. It’s more typical task for all C programmers, rather than iPhone devs.

how to random float number from 0.5 to 2.0

x is an integer? otherwise it’s not possible

% in this case gives you the rest from division so:

5 % 3 = 2
18 % 4 = 2 (18 – 4×4 = 2)
20 % 4 = 0 (20 – 4×5 = 0);
6 % 3 = 6 (6 – 3×0 = 6);

I use this
x = arc4random()% 480;

and I get sometimes numbers that 500+ ?

how can it be?
