sage: A = Matrix(CC,3); A.parent()
Full MatrixSpace of 3 by 3 dense matrices over Complex Field with 53 bits
of precision
sage: B = A.n(20); B.parent()
Full MatrixSpace of 3 by 3 dense matrices over Real Field with 20 bits of
precision
IMHO .n() only should change the precision, no other conversion.
This is also the behaviour of .n() on ComplexField.
