Anything in an inner loop is fixed point, almost everything else is float for ease of programming. The only things converted to fixed point are after it is deemed a bottleneck. Write first, test second, then rewrite if necessary.

So floating point performance on these devices ain't half bad then? I haven't had nearly as much time as I would have liked to really benchmark. I've just started getting into hardcore coding on these things. I VERY much like ARM assembler so I wanna see what I can do with the MMX unit on the Intel PX series of processors.

I have work on the Nintendo DS which is running an ARM9. Did alot of assembler on there.

Actually floating point sucks, as Dan East pointed out in the other thread, it depends on how much you use it I guess, if you are doing a few thousand floating point ops per frame then youre probably ok, if youre doing tens of thousands then you will want to do fixed point.
