Sure you do (as someone working in modular forms)! Infinity is the

I guess you are right. In modular forms one actually works with the

I am attempting to build Sage 2.10.4 om Mac OSX 10.3.9 (PPC), and have

Thanks Martin,
I think the issue is that we want a version of our repository that has no
binary data in it for transparency. The virus part is just a possible
scenario that has been blown out of proportion because of the way I asked
the question, since I didn't understand it well enough myself :)
As a compromise between you and Jason Grout I just went through the
plot code
and made sure all the print statements are replaced by calls to the

Something else to try (did in a notebook, not command line) is some variant
of

p = plot(sin(x), 0, 0.01)
p.show(xmin = 0, xmax = 0.02, ymin = 0, ymax = 0.02)
Hopefully this helps with the xmin -- xmax problems at which I too have

In my opinion this is not over-engineered. This is the canonical way

Recently while working on the gfan interface I starting thinking about

sure how it should be organized. The classes I created in gfan

Hello folks,
this is 2.11.alpha2. It is a little later than I had hoped and
planned mostly due to the fact that Easter and Spring break
put somewhat of a damper on development. So far we merged 111

There were fixes all over the map. This build should now also
