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 be one way to embed this into AA, as this way has already been chosen. However, we still get two ways: sage: Q.embeddings(AA) [ Ring morphism: From: Number Field in x with defining polynomial x^2 - 2 To: Algebraic Real Field Defn: x |--> -1.414213562373095?, Ring morphism: From: Number Field in x with defining polynomial x^2 - 2 To: Algebraic Real Field Defn: x |--> 1.414213562373095? ] How can I programmatically chose the right one? It does seem to me that I can't be the only one to expect that sorted(...) will work on lists where the members all belong to fields with embeddings... Currently, not only does this not work, but no error message is produced.... Do you think it is worth me making a ticket for this?
