Comment #9 on issue 1731 by asmeurer: fraction can be more flexible http://code.google.com/p/sympy/issues/detail?id=1731
As I noted above, fraction can deal with assumptions on the exponents. Also, fraction seems to be a full algorithm whereas as_numer_denom is implemented method wise on the classes (recursive). So the work seems to be duplicated. I wouldn't be surprised then if one of them ends up being capable of doing what the other can. I vote that we put all of the code in as_numer_denom and make fraction a wrapper around it (or get rid of it). Looking at the fraction code, it could be all implemented as methods, so I we should just go through and make sure that there is nothing fraction can do that as_numer_denom can't. Also, let's put the assumptions flag in as_numer_denom. -- You received this message because you are listed in the owner or CC fields of this issue, or because you starred this issue.
