it also needs a bit of work on py3 side - I notice that there is no from __future__ import division in the file I hack on, and adding it breaks some stuff.

OK, done. I wonder how much code in Sage still needs to be dealt in regard of py3 division. We certainly seldom want automatic conversion into floats...

  • Status changed from needs_review to positive_review

ok, thanks.

Concerning division, this file was maybe one of the largest can of issues remaining.
