rnd

returns a random number between 0 and n - 1 inclusive
number rnd (in n integer);
Description

The rnd function returns a random number between zero and n - 1, inclusive.

Randomize initializes the random number generator.

The random number generator is initialized after the clock at first usage, so the produced sequences will be different each time unless specifically initialized.
