New description:
{{{
Here is a (small) patch which includes some explanation and references in
the docstrings for totallyreal_rel.py.
The roundoff error is a bit mystifying to me, but in any case I
believe I fixed it in the patch: just expanding the bounds works, and
seems to only slow it down by a small amount.
In truth, I think the issue has to do with the fact that math.floor
and math.ceil return float64 not ints, and so I have to coerce these
ints, but I couldn't verify this.
