Operator precedence in expressions
The rules that determine the order for evaluating an expression with more than one operator are:
- An operator in a statement enclosed in parentheses takes precedence over operators that are not.
- Operators of unequal precedence are evaluated according to precedence, from highest to lowest.
- Operators of the same precedence are evaluated from left to right.
Operators not enclosed in parentheses are evaluated as follows:
Precedence Level | Name | Symbols |
|---|---|---|
1 (Highest) | Parentheses | ( ) |
2 | logical negation bitwise complement | NOT ~ |
3 | Multiplication division modulus (remainder) exponent logical and bitwise and bitwise right shift bitwise left shift | * / MOD, % ** AND, && & >> << |
4 | Addition subtraction logical or bitwise inclusive or bitwise exclusive or functions | + - OR, || | ^ |
5 (lowest) | Equal not equal less than greater than less than or equal to greater than or equal to | EQ, == NE, <> LT, < GT, > LE, <= GE, >= |
