I mean that you'll still be using fixed point numbers, but often you can get away with not needing fixed point operations.  To multiply or divide your fixed point number by an integer for instance is not the ** operation but is actually the regular multiplication which is what calc84maniac was talking about.  Sine and Cosine multiplication can also be done without the ** operation like I did in the cube example since you don't care about the decimal part of the number when drawing to the screen anyway so it doesn't matter that it gets clipped off.
