Comment #2 on issue 1945 by smichr: Fix as_numer_denom() docstring and add
Expr to the Sphinx docs
http://code.google.com/p/sympy/issues/detail?id=1945
That's a comment directed toward the idea of processing Eqs as has been
discussed
recently, but I added that in the code so that anyone being tempted to make
the
change would see that note. We don't have a good mechanism for including
such
comments that document possible changes to the code that don't work at
present. There
are other such examples that I have found useful, e.g. in mul.py
# Unfortunately, this isn't smart enough to consider combining into
# exponents that might already be adds, so things like:
# z - y y
# x * x will be left alone. This is because checking every
possible
# combination can slow things down.
Also there is the whole issue of where to include the docstrings for
methods:
- is there even a way to see the docstring of a method?
- when a method is subclassed should the main class instance have all the
docstrings
or should they be in the subclassed methods? e.g. "def as_numer_denom"
appears in
exponential, numbers, powers, mul, expr, basic, and add.
