I would like to understand Sage behaviour better. I just found out that
Sage is different from Pari when it comes to user input of values:
sage: Ei(1.1).n(100)
2.1673782795634028985887198360
sage: Ei(11/10).n(100)
2.1673782795634028235837873423
while in Pari:
? sin(1.1)
%1 =
Hello.
I do not think that is really a convention, but it is very logical because
1.1 can also be a float result given by Python. But floats and decimals are
not the same due to the ways operators act on them.

Your last comment is good.
Maybe you can use Decimal(1.1) to avoid confusion.

Oh, I forgot : it is indeed weird that faces may not exist in your
version of Sage even though trace_faces is already deprecated,but
everything seems to be fine in Sage 6.2.beta5. Sorry for that, I don't
know where it comes from, but it will be fixed if you update your
install :-)

Hello !
for a simple graph, trace_faces() gives the expected answer for the faces
of a planar graph
That's a good news :-D
the face that should exist between just nodes 3,4 and 5 is not found, it's
replaced with a face around nodes 1,2,3,4,5. Any ideas what is wrong, or
Nathann,
Thanks for your help! I'm fairly new to both Sage and graph theory, but I
understand the difference you point out, and it looks like the trace faces
function is giving me accurate faces for some valid planar embedding- just
not the one I thought it was working on. I spoke with a

Pari works with multiprecision by default, so you're getting more digits
here:

I think that Ralf's point is the following
print (4.001^2).n(300)
print ((4001/1000)^2).n(300)

Christa,
The problem is not with the code, but your expectations of it (which
may be valid, but that would be a feature request and not a bug). You
expect the code to look at your planar position dictionary, and gin up
an embedding from that. That is not a bad idea, and possibly a good
feature

Hi,
I'd like to report a bug in sage. There seems to be a problem with the
functions that check whether two quadratic forms over Z are
equivalent.
My default browser is firefox
when i type *$ sage -notebook *it opens in firefox.
Is there a way to specify other browser like *chromium-browser*

Should need only setting SAGE_BROWSER. See

Thank You Very much.
Now I will be able to make a unity launcher for sage.
