I fully accept the following is probably user error due to having not picked an embedding of the field.
sage: GaussianIntegers = NumberField(x^2+1, 'I').ring_of_integers() sage: A = GaussianIntegers([2,1]) sage: print A I + 2 sage: print A.n() <lots of junk> RuntimeError: maximum recursion depth exceeded while calling a Python object Still, this seems like not the most helpful error message; shouldn't it tell me to do (something like) this? sage: GaussianIntegers = NumberField(x^2+1, 'I', embedding=CC.gen()).ring_of_integers() sage: A = GaussianIntegers([2,1]) sage: print A.n() 2.00000000000000 + 1.00000000000000*I - kcrisman -- You received this message because you are subscribed to the Google Groups "sage-support" group.
