- You can use the plus operator to find the sum of two integers.
- Plus also works for floating point numbers, which is remarkable
- because floating point arithmetic, internally, is very different
- from integer arithmetic. Like plus, most built-in operators have
- more than one function, in that they perform differently when
- applied to different types. However, all built-in operators are
- not defined for all data types. For example, multiplying
- characters, or subscripting an integer is a syntax error.
