Comment:
Thanks Mike! This looks great.
Just by reading the code, I have one minor problem: Isn't the test `self >
0` too costly if the expression still contains variables? Maybe we should
convert to `RR` first and do the comparison there, similar to the way
Gonzalo handled this in #9627. This would also raise an error earlier
instead of going through maxima for the comparison and waiting for floor
or ceil to complain.
