Hello,
I've recently been creating some diagrams of trees with sage and have
run into some difficulties getting the graphs to look decent. I have
frequently run into issues with labels of vertices overlapping. Is
there anyway to enforce a distance between vertices or otherwise
ensure that the labe
The best way is probably to use mpmath.mpmath_to_sage(). Just note
that you have to provide the desired precision as well as the number
to convert.

xs was the list of x coordinates which I created with range

First off, I know that this is specificaly a SAGE issue, but I can't
find a matplotlib list, so I'm hoping that someone here can help. I
recieve an error when executing the following code in the notebook:
#Create the graph
import pylab
pylab.clf()
pylab.figure(1)
pylab.plot(xs, bits24_original, l

I have recently been using save_session a bit, and I uncovered what I
believe is a bug. If the worksheet of the session that I'm trying to
save contains a cython function, then load_session chokes. For
example:
var1 = 1
var2 = 2
var3 = srange(1,1)
var4 = range(1,3000)
var5 = 1234.123456

Thanks, it works once I use your link.

I just tried to access the wiki, and it keeps giving me this message:
Warning:
You triggered the wiki's surge protection by doing too many requests
in a short time.
Please make a short break reading the stuff you already got.
When you restart doing requests AFTER that, slow down or you might get
precision to the
requested, but overall, I didn't see a single major deviation
(although that obviously isn't concrete proof).

he .c file that cython generated, it seems to be
doing a lot of conversions as simply initializing sum_current took
almost 20 long lines of code.

I have recently been experimenting with converting some simple python
functions that I have made into cython. I have been quite impressed by
how simple it is for the massive speed increases that I have seen.
However, one thing that is mildly annoying at times is the limitation
to double precision

I have noticed recently that when evaluating the EI function at any
number over 20, it adds 2pi i, which shouldn't be there. After looking
at the code it appears that it uses scipy, so the error is probably
there. However, when looking for alternatives, I found the

I recently upgraded to the new version (3.1.4), and I can't view any
of the worksheets that I create. When I open up the notebook, no
worksheets are present even after I created a new one. I checked the
sage_notebook folder, and the files are being created, but for some
reason they are not showing

Thanks again to everyone who tried to assist me. I was able to use the
incomplete gamma function already in sage to compute Li(x) for complex
inputs. For the speed that I need this works fine. However, this
should be impetus for me to try and learn Cython.

After a little more searching, it appears that I should use a Pseudo
tty( right?). However, the programming guide gives no information on
how to actually do this. Any help would be greatly appreciated
(copying and pasting input and output is less than ideal).

Is there any way for SAGE to calculate Li(x) (logarithmic integral)
for complex inputs?
