I don't know the history of this choice or what we should be doing generally. -1 for polynomials with only positive degree seems like a computer science workaround, but for the LaurentPolynomialRing it just seems wrong? I think it's more than just a CS workaround. It has its roots in dimension considerations: the space of polynomials of degree at most d is (d+1)-dimensional. WIth that convention, 0 having degree -1 makes perfect sense. For deg = - ord_infty it should definitely be -oo, though, and for Laurent polynomials the dimension argument doesn't work. -- You received this message because you are subscribed to the Google Groups "sage-devel" group.
