I'm working on a script that requires the computer to chose a random number,
either 1, 2 or 3. I looked in a vbscript source book and it gives the
following example:

Randomize
GetRandomNumber = Int((3 * Rnd() + 1)

The author says the Rnd( ) function generates a random number between 0 and
1. The Int( ) function, which returns the integer portion of a number,
executes, multiplying 3 times the randomly generated number and then adds 1
to it. The final result is a randomly generated number with a value between
1 and 3.

If I do the math 3 times 0 is 0 and add 1 is 1. 3 times 1 is 3 plus 1 is 4.
Am I not understanding something in this equation? If not I would
appreciate an explanation. Thanks, Jim
