Rnd function Rnd Function Returns a random number between 0 and 1.

Syntax: Rnd [(Expression)] Return value: Double Parameters: 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. Example: Sub ExampleRandomSelect Dim iVar As Integer iVar = Int((15 * Rnd) -2) Select Case iVar Case 1 To 5 Print "Number from 1 to 5" Case 6, 7, 8 Print "Number from 6 to 8" Case Is > 8 And iVar < 11 Print "Greater than 8" Case Else Print "Outside range 1 to 10" End Select End Sub
