> it would be interesting to look at this thread (well the rounding thread)
from a point of view of how many siginificant digits do i need so that i'm
not significantly biasing my calculations ie: my robot won't be off course
more than a 1" after traveling 20' using my optical encoder or accelerometer
or whatever.

Well, that kind of depends on how complex your computations are and how
loose the mechanical tolerances are on your robots (mechanical error vs.
round off error).  --My robots don't need many significant digits at all...
