Hi,
One of the real joys of the holiday season is the opportunity to say Thank
You to all Sage developers, and to wish them, users and all who are dear
and near the very best for the New Year!
I noted five minor issues:
1) Developer’s Guide v5.5: typo
Howver, in order to do development in the Sage notebook, including
submitting change requests to upstream, we highly recommend installing Git
(see below).
2) Output [1,1] of Solve intended?
sage: var('x,y')
sage: print solve([x^2-2*x*y+y^2==7],x,y,solution_dict=True)
([{x: y - sqrt(7)}, {x: y + sqrt(7)}], [1, 1])
3) NZMATH
sage: install_package('nzmath')
sage: from nzmath import *
sage: ecpp.cornacchiamodify(-7,29)
Traceback (most recent call last):
...
ZeroDivisionError: reduction modulo right not defined.
Problem: arith1.modsqrt not an Integer but IntegerMod. N.B.: Updating to
NZMATH version 1.2 could be considered too; reference
#11421<http://trac.sagemath.org/sage_trac/ticket/11421>
4) Matrix output
still<5)%09https:/groups.google.com/forum/?fromgroups=#!searchin/sage-support/roland/sage-support/OWB-4Oy34JI/4rVFdiusQYsJ>inconsistent
with 0.00
Sage: A = matrix([ [-1.0, -1.0, 0.0, 1.0], [1.0, -1.0, -1.0, -2.0] ])
Sage: A.n(2)
[-1.0 -1.0 0.00 1.0]
[ 1.0 -1.0 -1.0 -2.0]
5) Can’t we close http://trac.sagemath.org/sage_trac/ticket/9298?
P.S.: As Google allows tags, maybe reserving a name as minor_issues is
handy.
Virtualbox 4.2.6; Sage version 5.5ova
