Comment:
The discussion on sage-devel available here:
https://groups.google.com/forum/#!searchin/sage-devel/barycentric/sage-
devel/HubsPplvkE4/gw0avDkWCQAJ
Led me to only test for rational polytopes. The barycentric subdivision is
fast enough on the rationals and will ultimately lead to problems in RDF
in any case, therefore I would say it is not necessary to test it.
I would say it is also not necessary to warn the user, as the user should
know that doing such computations in RDF will lead to errors.
Is that reasonable?
The current last commit made test pass on sage-6.9.
