Operator precedence
Higher levels bind tighter. For example, * binds tighter than +, so multiplication happens first. Use parentheses to override.
| Operator | Description | Level |
|---|---|---|
?? |
Null coalescing | 0 |
|| |
Logical OR | 1 |
&& |
Logical AND | 2 |
== |
Equals | 3 |
!= |
Not equals | 3 |
< |
Less than | 4 |
> |
Greater than | 4 |
<= |
Less than or equal | 4 |
>= |
Greater than or equal | 4 |
+ |
Addition, string concatenation | 5 |
- |
Subtraction | 5 |
* |
Multiplication | 6 |
/ |
Division | 6 |
! |
Logical NOT (unary) | 7 |
Unary ! binds tighter than any binary operator, so it negates only the operand right after it: !a && b is (!a) && b. To negate a larger expression, parenthesize it: !(a && b).
The full grammar is in the EBNF reference.
