Comment:
Yes, though I wouldn't say completely broken, since not every doctest
fails, correct?
Other issues:
In symbolic/integration/integral.py, there is one integral which has been
improved, and one which seems to affected by the rational approximation
thing, but wasn't before. There is also an integral (in that file, I
think) which Maxima can now do, and we need to replace it with one Maxima
can't do. There is also a slight change in the numeric value because of
this, but that wasn't the point of that doctest.
The binomial issue seems easy to fix, but apparently now binomial(n,n)=1
for all n in Sage, but not in Maxima. Should we change Sage, or do what
Jason recommends (assume n>0 or something)?
And in interfaces/maxima.py there are a lot of erros where Maxima loads
like
{{{
;;; Loading #P".../local/lib/ecl/cmp.fas"
;;; Loading #P".../local/lib/ecl/sysfun.lsp"
}}}
as well as of course the Maxima version being wrong and, oddly, the
following:
{{{
sage: maxima.eval('sage0: x == x;')
Expected <Error>
Got:
'x'
}}}
which is not good at all if real, but maybe just means Maxima changed
something minor?
The plot3d one is not too significant, I think. I haven't looked at the
other ones.
Anyway, obviously 'needs work' until someone posts a fairly comprehensive
patch.
