Comment #35 on issue 1598 by asmeurer: New polynomials manipulation module http://code.google.com/p/sympy/issues/detail?id=1598
You are right. fraction() is like as_numer_denom() except for a little "magic", but I think we should move all of the code there into as_numer_denom() as it is duplicated (actually the only "magic" it performs that as_numer_denom doesn't as far as I can tell is that it handles assumptions on variable exponents, which as_numer_denom should maybe be doing the same with a similar keyword argument. See issue 1731). To Chris, separatevars() does want to use normal factor. That way, it can separate 1 + x + y + x*y. If you are doing it right, you should see a nice xpass test for it with the new polys module (actually it needs to be fixed to not bother with PolynomialError anymore). -- You received this message because you are listed in the owner or CC fields of this issue, or because you starred this issue.
