You may be able to select some more complex math functions (like sqrt/sin)
at run-time, but for plain arithmetic this usually nullifies the "hard float"
advantage, see AmigaOS mathieeedoubbas.library. Most often people will
just use hard-float with a trap handler that emulates the instructions
if a FPU isn't available. Yes, that's slower than soft-float, but you
rarely use a FPU-less CPU for math anyway.
