New description:
The code for numerator is currently
{{{
#!python
def numerator(self):
"""
Returns the numerator of this symbolic expression. If the
[...]
"""
return self.parent()(self._maxima_().num())
}}}
Using Pynac should be much faster.
The patch wraps numer, denom, numer_denom and normal from GiNaC and fixes
a
bunch of wrong sphinx markup in {{{expression.pyx}}}.
