Comment(by vbraun):
I didn't know about "-coverage", but it passed doctest without errors or
warnings with sage-4.1.1. The cast problem must be from Sage 4.1.2, I
guess.
If you want to add the missing test that would be great. Email me if you
have questions / comments.
I tried to stick to the following general philosophy for the polytopes
class:
* if the vertex coordinates can be chosen rational, then the polyhedron
should be in QQ
* otherwise, the polyhedron should be over RDF by default. A rational
approximation can be optional via a "field=QQ" parameter.
Floating point coordinates are fine with cddlib as long as the input is
sufficiently nondegenerate, and polytopes defined by vertices are no
problem.
