I think the difference is due to limited wordlength, which
means rounding errors and overflow. For instance, when you
multiply by 100 before deviding, you can have an overflow.
For accurate calculations you should group together numbers
with the same order of magnitude. By dividing first you
reduce the output of rand to a value between 0 and 1 (if I
understand rand correctly) and then scale it to a number
between 0 and 100.
