I recall spending days playing with tricks of integer math to get resolutio=
n and scaling without using floating point. "Because floating-point takes t=
oo long" A couple weeks ago I was walking a junior (three months out of col=
lege, so green I have to water him) through a recent project. I was going d=
own the path of integer math, he declared them as floats.... I was about to=
 go into full lecture mode when we actually benchmarked the code - the proc=
essor still spends 99% of it's time waiting for new data. There's just noth=
ing to be saved in that project to justify the time it takes to "improve" t=
he code.



True, if that's all you ever want to do with that system.  I still think it=
's a bad habit though. =20
