Return the coefficient ring of the series ring R.
Return the power series ring which is the integer ring of the laurent series ring R.
Return the laurent series ring which is the field of fractions of the series ring R.
Return a series ring identical to the series ring R but having precision r.
Return the series ring identical to the series ring R but having coefficient ring C.
Return the residue class field of the series ring R (which will be the same as the coefficient ring of R) and the map from R into the residue class field.
Return the precision of the fixed precision series ring R. If R is a fixed precision power series ring, then this is the fixed absolute precision for all elements of the ring. If R is a fixed precision Laurent series ring, then this is the maximum relative precision for all elements of the ring.
