Yes, there are, with the exception of accumulators like sum, etc.  We
also won't guarantee that unit conversions will not over/underflow,
but that should be okay for your situation.  Today I started on the
process of doing particles in native bits, and fluids will come a
while after that.  Mostly it's a problem of getting the Cython
routines to use "fused types."
