Returns a random number between 0 and 1.
Rnd [(Expression)]
Double
Expression: Any numeric expression that defines how to generate random numbers.
Less than zero: Always returns the same random number.
Greater than zero: Returns the next random number in the sequence.
Zero: Returns the random number that was last generated.
Omitted: Returns the next random number in the sequence.
If the same number is passed for each successive call to the Rnd function, the same random-number sequence is generated. This is because the Expression parameter is used as a starting point for the next number.
The Rnd function only returns values ranging from 0 to 1. To generate random integers in a given range, use the formula in the following 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
