not really -- if you are moving from matlab to python, you are going to be
using numpy and scipy -- we really don't need to spell similar
functionality differently than scipy does.

In regard to the "special values", and exact results -- a good math lib
should return results that are "exact" in all but maybe the last digit
stored. So you could check inputs and outputs with, e.g. math.isclose() to
give people the "exact" results. -- and keep it all in floating point.
