The patch by Robert Marik attached to #9835 solves the problem you
show below.
Applied the indicated patch, same outcome:
reset()
var('g t')
x = function('x',t)
forget()
assume(g 0)
de = x - g * diff(x,t,2)
Suppose I define
h1 = '2bd5427c'
h2 = '65ef24ab'
Then I can obtain their exclusive-or by first converting to an
integer, and back again after:
hex(ZZ(h1,16)^^ZZ(h2,16))
which produces the correct value
'4e3a66d7'

I have a C++ function I want to call from sage. I have attempted to
follow the example in
http://docs.cython.org/src/userguide/wrapping_CPlusPlus.html
This was unsuccessful. The C++ class is not recognised. The problem
seems to be that this is Cython v0.13 whereas sage 4.5.2 (which I am
using)
Hi,
For some reason I don't know the output of the help pages (like the
tutorial) have tiny scroll boxes around.
I am using chromium. With firefox there is not such problem, but the

And why is it? I do an assignement but it doesn't accept it:
TypeError: Computation failed since Maxima requested additional
constraints (try the command 'assume((a-1)*(a+1)0)' before integral
or limit evaluation, for example):
Is (a-1)*(a+1) positive, negative, or zero?

So sometimes even if you *do* have assumptions working properly, there
are so many paths in the decision tree that it would be very hard to
do this sort of thing. I hope that helps you - I guess to me that is
