[gameprogrammer] Re: Diff Between 2 Angles

% or modulus doesn't always work right on negative numbers I think...
 Or for some reason I had problems with it (memory is fuzzy, more
than 2 days old.)  fmod() might not have an issue.  But then I doubt
the loop will be called more than twice although I don't know exactly
what the inputs can look like in the extremes.  Is fmod() (a function
call) faster than the loop and a subtraction?  I don't know.  I was
also maintaining sign of the difference between angles not being sure
if the user wanted it or not.
