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 The operator < and > do not correspond : sage: sqrt3 > Q.zero() True sage: Q.zero() < sqrt3 #not ok False Other similar behavior : sage: -sqrt3 > Q.zero() #not ok True sage: -sqrt3 < Q.zero() False sage: sqrt3 < Q.zero() False sage: sqrt3 < -sqrt3 #not ok False sage: sqrt3 > -sqrt3 True sage: -sqrt3 > sqrt3 #not ok True sage: -sqrt3 < sqrt3 False Is this known?
