I want to check if a number is set to infinity or NaN. So I tried this

But this doesn't work when x=a/b with a very small b, so that x

Hello,
I just upgraded from 3.0.5 to version 3.1.1 and several things aren't

doesn't work when I copy examples directly from the documentation.

Hi,
When computing Eisenstein series with a given character, Sage may
return some forms with a wrong character. The following lines show an
example of this:
sage: G = DirichletGroup(7)
sage: E = EisensteinForms(G[4]).eisenstein_series()
sage: E[0].character() == G[4]
False
The problem appears
Just out of curiosity, what did you have to add? Your latest code

My computer is much older, and always overloaded.

My principle is - program must run as fast as it is possible. It's
reason to move.

I'd like to include an .eps graphic in my sage-notebook output.

I haven't found any useful documentation on the Share and Publish

I think I've found a documentation bug, but perhaps I just don't know

The plot() function uses the color or rgbcolor options.
The implicit_plot() function does not recognize this, but requests

Hi Peter,
I've actually been planning on going back and cleaning up/speeding up
the Eisenstein series code at some point in the near future anyway.
I'm on vacation this week, but I'll look at this at the beginning of
next week. In the interim, this is now:
It works with not z.is_infinity().
Thanks :)
