    Post ATAN2 Function replacement

    I am looking for the math that performs the same thing as the ATAN2 function used in Excell. The problem is, in VB the only function available is ATAN.

    Anyones help would be greatly appreciated.

    ATAN2(x,y) is the same thing as ATAN(y/x).
    There are 10 types of people in the world - those that understand binary, and those that don't.

    Code:
    If X Then
        Atan2 = Atn(Y / X) - (X > 0) * 3.14159265358979
    Else
        Atan2 = 1.5707963267949 + (Y > 0) * 3.14159265358979
End If
    Use

    writing haskell makes your life easier:
    reverse (p (6*9)) where p x|x==0=""|True=chr (48+z): p y where (y,z)=divMod x 13
    To throw away OOP for low level languages is myopia, to keep OOP is hyperopia. To throw away OOP for a high level language is insight.
