Classes Complex and Rational are good examples of programmer-defined types that emulate the properties of built-in C++ numeric types. The objects of these types can be operated on by using the same set of operators as that used for an ordinary numeric variable. This supports the C++ goal of treating programmer-defined types in the same way as C++ built-in types are.
This analogy, however, is not complete. You can apply a number of operators to variables of numeric types that you cannot apply to Complex or Rational objects. Examples of such operators are modulo division, bitwise logical operators, and shifts. Of course, you can overload these operators similar to arithmetic and comparison operators, but the meaning of ...
