I notice that ratinterpol always calls rat on its arguments. Is there
a particular reason for this?
I was just playing around with ratinterpol with float and bigfloat
points, and the result is always rational. I could just float or
bigfloat the result, but I was wondering why ratinterpol always
rationalizes floats. I guess in practice it may not matter
(Perhaps the documentation for ratinterpol should mention this, too.)
