This function will work the same way is the DB built-in function. Just for those who like to know how things work.

the two distances (x,y) you specify are the legs of a triangle. You could figure out the length of the hypotneuse and use sine or cosine, but its not needed. Tangent is used to find the angle given two legs. Atan to get the angle of that tangent value.

Nice, usefull snippet! I know this was probably only to show how it works, but if with the way you have it written, if x# does equal zero, your going to get a divide by zero error. I'd re-write it like this:



Hoooowwwwllll!!!!

That's odd. That never occurred to me. I know I've tested it x=0 I'm sure, and I got no error.
