As long as you don't use sin/cos (oops, no 3D, no polar coordinates,
no FFT), sqrt (oops no lenghts), pi (oops no non-polygonal surfaces)
or ln/exp (oops, a lot of things are gone there).

Working with rationals is not that realistic nowadays except in things
like mathematica, maple and friends.  Fixed-point though is still very
realistics, it's just a different precision/scale tradeoff than fp,
and one you control.

  OG.
