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 |
|---|---|
| 0 | ( ) |
| 1 | . |
| 2 | BIT PTR BYTE PTR WORD PTR NEAR PTR FAR PTR DATA3 DATA4 DATA8 DATA16 DATA32 DATA64 DPPx SEG PAG SOF POF BOF |
| 3 | HIGH LOW BYTE0 BYTE1 BYTE2 BYTE3 BYTE4 BYTE5 BYTE6 BYTE7 WORD0 WORD2 WORD4 WORD6 NOT Unary + Unary - |
| 4 | * / MOD |
| 5 | + - |
| 6 | SHL << SHR >> |
| 7 | AND & OR | XOR ^ |
| 8 | EQ == NE != LT < LE <= GT > GE >= ULT ULE UGT UGE |
| 9 | SHORT |
