Well, same problem 2 and 3, but not necessarily 1. I don't think you'd need to conform to every last IEEE rounding rule if it's the "fast" version.

I believe the 'f' stands for 'float' (since the normal functions return double). This should be faster, since it need compute fewer bits of precision, but it is still returning the correct result, rounded to a float. I might have assumed incorrectly here, though :)
