A Result object is also characterized by two other integer values:
The tensorial order of the values it stores. This integer may be 0, 1, 2 or -2 corresponding to scalar, vectorial, symmetric tensorial or non-symmetric tensorial values.
The format of the result. This value may be 1 (Real values), 2 (Complex Result in rectangular format) or 3 (Complex Result in polar format).
Methods used to manipulate these data are described in section I.4.6.1. These two integers are attributes of the class.
