Operators Foundation
The compiler identifies operators as one or two specific characters in the program code. An operator specifies how values are to be manipulated and completes an operation using one or more operands. The Xbase++ compiler recognizes the operators in the following list:
Operators in Xbase++
| Operators | Description / Operation Performed |
|---|---|
| & () [] -> : | Special operators |
| ++ -- | Prefix increment/decrement |
| - + | Unary minus/plus operator |
| ** ^ | Exponentiation |
| * / % | Multiplication, division, modulus |
| + - | Addition, subtraction |
| = == != <> # <= >= < > $ .IN. | Comparison operators |
| .NOT. ! | Logical negation |
| .AND. | Logical AND |
| .OR. | Logical OR |
| = := += -= *= /= ^= **= %= | (combined) assignment operators |
| ++ -- | Postfix increment/decrement |
The operators are listed in the table in order of descending precedence.
