Funny story I've heard. Apparently, one young engineer once decided to REALLY simplify sin(x), when writing this function in assembly, they decided to just simply return, not the tiny small x which is approximately the correct answer, but, instead, 0 (Well, we DID say x is small, right? so it's close to 0, right?) The craft this sin(x) approximation was supposed to be controlling, had bad problems with the rudder never deflecting, for "some strange mysterious reason". <VBG> Be careful not to OVER-optimize, I guess is the moral of this story... Software testing can be a good idea, huh?
