Hello,
I'm writing a very initial version of a code generator. I would like to add
proper tests for the generated c code. The test will involve a compilation with
gcc and linking against a small c program that tests the output of the function
for several inputs. If some outputs are wrong, the n

Just noticed an odd behavior: does anyone know why a power would be
changed to real by simplification if that power is a term in a
division expression?
###
>>> a,y=var('a y')
>>> simplify(a*y**5)
a*y**5
>>> simplify(y**5/a)
y**5.0/a

I'm not sure what's different. I just synced my python sympy with the
git master sympy and obtained the same result:
PythonWin 2.6.1 (r261:67
Once again, I cannot reproduce this. What version of python are you
running? Try doing "from __future__ import division". It is
reminiscent of things like 1/3 returning the float 0..
Also try simplify(sympify(y**5/a)). Does it only do this if you call
simplify? If so, cou
