Hi Sage-devel,
I am currently experiencing some problems when comparing elements of a
QuadraticField. See below.
sage: Q.<sqrt3> = QuadraticField(3)
sage: 0 < sqrt3
False
sage: RR(sqrt3)
1.73205080756888
[...]
Is this known?
Yes, cmp() for number field elements is arbitrary, as they don't have
(canonical) real embeddings in general. There are a couple of tickets
to address this.
