 Replying to [comment:109 fbissey]:
 > Updated the first patch for polyhedra.py, split transcendental.py in its
 own patch. I lowered the precision tested in the last numbers so that
 results from 32 and 64 bits are not different.
 Here the fix_transcendental patch fixed the associated test on x86 but now
 the test fails on amd64:

 {{{

 This is odd! I wonder what changed? Previously this test must have
 returned ...67 and not ...63 for it to pass.
