I suppose it would be laurent polynomials if you were writing a function
with a denominator that was a simple power of the indeterminate.
ratexpand actually takes the rat() form and merely writes it out
differently. It separates the numerator into monomials and the
denominator is repeated under each monomial.
If it helps to think of it as Laurent polynomial "whenever possible"
I think that is correct, but the term was never used by the
programmer (as it happens, me..).
