Operators
Operators may be unary (requiring one operand) or binary (requiring two operands). The combination of an operator and its operand(s) is an expression. Parentheses may be used in expressions with multiple operators to specify the order in which operators are evaluated. If no parentheses are used in an expression, operator precedence determines the evaluation order.
Following is the operator precedence table:
| Level | Operators |
|---|---|
| 1 | ( ) |
| 2 | NOT HIGH LOW BYTE0 BYTE1 BYTE2 BYTE3 WORD0 WORD2 |
| 3 | Unary + Unary - |
| 4 | * / MOD |
| 5 | + - |
| 6 | SHL SHR |
| 7 | AND OR XOR |
| 8 | EQ = NE <> LT < LTE
<= GT > GTE
