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.

Пример


Sub ExampleRandomSelect
Dim iVar As Integer
    iVar = Int((15 * Rnd) -2)
    Select Case iVar
        Case 1 To 5
            Печати "број од 1 до 5"
        Case 6, 7, 8
            Печати "број од 6 до 8"
        Case Is > 8 And iVar < 11
            Печати "поголемо од 8"
        Case Else
            Печати "надворешен опсег 1 до 10"
