Looking in rings/complex_number.pyx, it looks like it a simple lex ordering. I would bet that this is because people would be annoyed that you get an exception if you tried to sort a list of complex numbers, even though you can't. :) --Christopher On Wed, Jan 25, 2012 at 12:22, Volker Braun wro

If we have possible confusions about the numberiung, we should give them complex number identifier. So, 37, 37 + i, 37 - i, etc. Who knows which one comes first then? --Christopher On Wed, Jan 25, 2012 at 09:39, Sébastien Labbé wrote: > > > I thought last time we had this discussion (for 35.5
