I dunno really.

You could always get some existing source and compile it yourself to use the amiga math libraries.
Pity, a lot of 68060 stuff assumes FPU and with good reason - the FPU in the 68060 is damn fast compared to any other 680x0. So much so that it even gets used for some integer calcs too (especially 64-bit mult/div emulation).
int p; // A

Not too odd, considering the 68060 doesn't have hardware mul64/div64, unlike the 020-040 CPU's. Running those via 68060.library really doesn't cut the mustard. :-)


What I meant was it uses fpu over doing the same job in integer emulation code beacuse it's so fast at floating point...
