Expression: Has no effect, is ignored if provided.

The Rnd function returns decimal fractions ranging from 0 (included) to 1 (excluded) according to a uniform distribution. It uses the Mersenne Twister 19937 random-number generator. To generate random integers in a given range, use a formula like in the example below. A Randomize statement with a defined seed value can be used beforehand, if a predictable sequence of numbers is desired.
