This is indeed a bug. The logic was meant to handle the case '1.23' (a
decimal in the middle of the mantissa) as having three significant figures.

Oddly, it always seems to affect the first defined variable apart from x.
Thanks for the bug report.

Hello,
Could please someone with an apple help me debug the ticket
https://trac.sagemath.org/ticket/22257 (which stands as a current block on
our long road to python3, and was positive reviewed before it failed on
apple)
More specifically,
(1) apply the branch, run the tests:
sage -bt --long
Ok I think I just made a remark this is irrelevant to your actual question.
CC'ing Robert Bradshaw who I think wrote the relevant code for choosing
precision...

I am interested in Coxeter groups and have worked quite a bit on them in
Sage. So feel free to cc me on the eventual ticket ("tscrim") and/or e-mail
me if you have any questions if you don't want to post here.
As Miguel said, you should consider including this as an optional spkg or

I recommend you to start by reading the sage developer guide:
http://doc.sagemath.org/html/en/developer/index.html
It covers all the development process.
I am no expert in Coxeter groups, but from what I see, we already have
support for them in Sage. So I will assume that your software would pr

OK, I've answered to the ask.sagemath user accordingly. Please correct my

Hi,
I was surprised to notice the following behavior:

sage: r.parent()
Real Field with 57 bits of precision
sage: r =0.123456789123456789

Hi,
the following behaviour of Sage 7.5.1 and 7.6 (Ubuntu 16.04.1, 64-bit) is
unexpected:
sage: var('x y0 y1')
(x, y0, y1)
sage: y0.series(x)
1*x + Order(x^20)
sage: y1.series(x)
(y1)
Version 7.4 works fine.
Best,

Dear sage developers,
During my PhD I developed a C++ program to compute invariants of hyperbolic
Coxeter groups.
The program was published in the LMS Journal of Computations and
Mathematics and is now on GitHub: https://github.com/rgugliel/CoxIter
I am wondering if it could be included into SA
