Logical operators can only be used with arguments that can be evaluated to Boolean.
Boolean Operators
As the following table shows, the NOT operator is a unary prefix operator. This means that it takes only one argument and is placed in front of the argument. The AND, OR, and XOR operators are binary infix operators; they take two arguments and are placed between the corresponding arguments.
| Operator | Name | Expression | Resulting data type |
|---|---|---|---|
NOT | Logical negation | NOT bool | bool |
AND | Logical and | bool AND bool | bool |
OR | Logical or | bool OR bool | bool |
XOR | Exclusive logical or | bool XOR bool | bool |
