I have found something a bit strange for me: sage: xx=QQ(2) sage: xx.parent() Rational Field
ok... sage: xxc=xx.sqrt() sage: xxc.parent() Symbolic Ring Why not, but now: sage: M1=matrix(QQ,1,1,[2]) sage: M1.parent() Full MatrixSpace of 1 by 1 dense matrices over Rational Field sage: M1C=M1.cholesky() sage: M1C [1.414213562373095?] sage: M1C.parent() Full MatrixSpace of 1 by 1 dense matrices over Algebraic Field So, we have: xxc: Symbolic Ring M1C: Full MatrixSpace of 1 by 1 dense matrices over Algebraic Field and also: sage: mxx=M1C.row(0)[0] sage: mxx.parent() Algebraic Field sage: mxx==xxc True Why is xxc in Symbolic Ring and not in Algebraic Field? mxx and xxc are essentialy the same thing, no ? A bit strange for me... Yours t.d. -- You received this message because you are subscribed to the Google Groups "sage-support" group.
