Boolean logic is fairly simple (AFA I'm concerned). I believe my
translation of your arctan2() showed that. Granted, I reversed a couple of
signs (and always reversed twice to undo the sign reversal), and used a
few sneaky tricks like "1-yeo" rather than "not yeo", but the logic is
still there. (I hope - see next comment)

Eep! You might just want to double check my routines if you're going
to use them in commercial software. I'm not saying they're wrong, but
they're probably provably imperfect... :)

Thanks,
Carl
