Devolve un número aleatorio entre 0 e 1.
Rnd [(Expresión)]
Double
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.
Sub ExampleRandomSelect
Dim iVar As Integer
    iVar = Int((15 * Rnd) -2)
    Select Case iVar
        Case 1 To 5
            Print "Número do 1 ao 5"
        Case 6, 7, 8
            Print "Número do 6 ao 8"
        Case Is > 8 And iVar < 11
            Print "Maior que 8"
        Case Else
            Print "Fóra do rango de 1 a 10"
    End Select
End Sub
