Rnd() ignores the maximum value

    If you run this example you'll see that rnd() never returns 1.

    Sub App_Start
    If n=0 Then
    End If
    Loop Until x=1
    End Sub

    Sorry. I admit that I skimmed over the documentation for rnd() (as short as it was). I've never seen a rnd function that ignores the upper limit before and assumed wrong. I was convinced this was a bug.

    No problem ;)
    This is how it behaves in C# and VB .Net.

    In the old days, in my zx spectrum ++, rnd only returned a value between 0 and....1, except for the ....1 so we ould get decimal of 0.1,0.2,....etc and we couldnt even state the max or min values.... now that was confusing....:signOops:

    ... max values were possible ...

    10 LET A = INT(RND*N)

    ... results for A are values from 0 to N-1 ... :)
