Radian to Degrees issue.

[Kyler Carlson]

Okay. I'm trying to find the measure of an angle. My code is what I think should be working but some funny things are happening. About 2/3 times, it doesn't even give me an angle and the other 1/3 of the time, the numbers are ususally between 50-90 or -50 through -90 though I don't know why. I have iscolated the problem to the _degree() thing but I'm not sure what's wrong with it. Many of the commented out things are my attempts at fixing it so i'll leave them in here. I might not of done something right so please try the things I tried again. Also, I am including the math.au3. thanks.
