I don't get that error, but several doctests fail expectedly since the docs 
haven't
been updated.

Could your problem be a Unix/Windows issue?

A lot of mpmath doctests are failing in sympy currently. I think they need to be
fixed, can you acknowledge?

GoogleCodeExporter commented 9 years ago 
Which ones? Possibly at least some of them have been fixed in mpmath.

Right now there are (passing) docstring doctests in calculus.py, functions.py,
elliptic.py and identification.py that can be run by invoking the .py files. 
There
should just be a way to run them all automatically.

Ondrej implemented a very nice doctest runner. Using it for sympy I figured out 
that
many doctests fail (because they were outdated -- some of them were never 
tested,
fundamental imports were missing). I fixed them, except for mpmath, because this
should be fixed here and I wanted to know your opinion.

There are quite a lot of tests failing:

I think most of those tests are outdated. Anyway, I'll make sure all doctests 
work 
as I'm revising the documentation per issue 92 (I just haven't gotten 
everywhere 
yet).

The last ones are interesting. 1.0001**-5 does repr to 0.99950014996500702 for 
me, 
on at least three different systems; why doesn't it for you?

Maybe a bug in Ondrej's doctest runner (it's not yet finished nor committed).

I'll wait until you revised the documentation before trying to fix it in sympy.
Please let me know if I can help you!

Closing this because it's either a bug in SymPy or no longer relevant.
