    I need to convert percent slope to degrees and would prefer not to use a table...I would like to use a formula, but I think I need to use a ArcTan to convert percent slope to degrees:
    Slope Degrees = ArcTan (Slope)

    I do not see an ArcTan function in Basic4PPC. Am I missing this?
    Does anyone know another way to arrive at the answer?
    Thanks so much!

    It is named ATan.
    degrees = 180 / cPI * ATan(slope)
