Hi David, thanks for your reply!
I was wondering if there is a way to automatically get the desired
embedding into AA. If I do:
sage: Q=NumberField(x^2-2,'x',embedding=1.41)
sage: x=Q.gen()
sage: float(x)
1.4142135623730949
Then, I've made a field with an embedding, so really there should only

Dear Emil,
There's a bit of a tug of war going on with comparison for number field
elements. On the one hand, it should always be possible to compare two
elements of a given number field, and the resulting ordering should be a
total order and one that's deterministic and quick to compute. On th
