RandRange

Returns a random integer between two specified numbers. Note that requests for random integers greater than 100,000,000 will result in non-random behavior. This restriction prevents overflow during internal computations.

Syntax

RandRange(number1, number2)

number1, number2

Integer numbers less than 100,000,000.
