Comment(by mhampton):
I'm thinking of changing the Inequality and Equation initializations to
have:
{{{
if polyhedron._cdd_type == 'real':
normal_norm = vector(data[1:]).norm()
data = [x/normal_norm for x in data]
}}}
This solves the problem I had above, and all tests pass. Some of those
tests include numerical polytopes. I also tested it on a few additional
high dimensional cases.
I won't make a patch yet since I suspect I will hear some counter-
arguments...
