Is there somebody out there who can introduce me to the art of How-to-use-SANE ?

I am writing an interactive simulation application (biomechanics) which
involves some heavy number crunching in the motion integration loop.
In particular the simulation may well go unstable and I need to catch that
before the Mac crashes... So I need to monitor the floating point operations
and I think that's what SANE is made for.

I would be happy to hear about how to do that in a reasonable way. For instance
I assume that not every single FP operation has to be checked but only a few
critical ones, right ?

Any advice welcome, example codes, pointers to references (pretty indirect, no?)
Thanks in advance.

PS: The application has 3D graphical output for the simulation (pseudo-real
time). Sofar I convert directly from floating point world coordinates to
integer screen coordinates. Would it be more efficient to use a type like Fixed
or Frac for the world coord's (in terms of speed ?)
