Hi all,
I'm trying to add some simple labels to plots, but axes_label appears
to not be working in sage-3.0.1. Ticket # 1508
(http://trac.sagemath.org/sage_trac/ticket/1508) reports
Is this a bug?
sage: 3 == pi
3 == pi
sage: i == i
I == I
Shouldn't this return False and True, respectively? I know this
works:
sage: 3 == pi.n()
False
sage: 3 == RR(pi)
False
but I sort of expect pi to act like the number pi when used with
things like == or , without using the .n()

Those are symbolic equations

Here's the situation: in some sage code that I'm working on, I have a
variable, say 'output_format', which tells sage how to print certain

Suppose I have a tuple x of distinct non-negative integers. Is there
a quick way to find the sign of this, as a permutation of Set(x)? (I
want to view x as the one-line permutation notation form, so (3,6,4)
will have sign -1, while (5,3,8,6) will have sign 1.)

I'm running into a coercion problem. I'm trying to define a class
SteenrodAlgebra (based on the Algebra class); there should be one
Steenrod algebra for each prime number p, and it is an algebra over
GF(p). For example, you can do
sage: A5 = SteenrodAlgebra(5)
sage: A7 = SteenrodAlgebra(7)

Yes, Sage caches some information so it doesn't have to do the logic
anew on each arithmetic

Ah, it looks like your __eq__ method is assuming that self and

this:
1) Use __cmp__ which

Yes, though that will mean something like A5

I'm just starting with Sage, and I must say, it makes a good
sage: is_FractionField(FractionField(ZZ))
False
Oy. This seems to be intentional: there is a doctest very similar to
this. It doesn't seem right, though. How hard would it be to change?
Is it worth it?
Along the same lines, partial fraction decomposition should work for
rational numbers; this
