Operators can be overloaded to provide more natural syntax for custom types. Operator overloading is most appropriately used for implementing custom structs that represent fairly primitive data types. For example, a custom numeric type is an excellent candidate for operator overloading.

The following symbolic operators can be overloaded:

+   -   *   /   ++   --   !   ~   %   &   |   ^
==  !=  <   <<  >>   >

Implicit and explicit conversions can also be overridden (with the implicit and explicit keywords), as can the literals true and false, and the unary + and - operators.

The compound assignment operators (e.g., +=, /=) are automatically overridden when you override the noncompound operators (e.g., +, /).
