The precedence of operators is as follows, from lowest to highest:
| = op= | assignment, shortcut operate and assign op can be +, -, *, /, >>, <<, &, ^, |, %, or **. = op= is not available in Expression Nodes. |
| ? : | conditional evaluation |
| || | logical or |
| && | logical and |
| | | bit or |
| ^ | bit exclusive or |
| & | bit and |
| != and == | inequality and equality |
| >, <, >=, and <= | greater, less, greater or equal, and less or equal |
| >> and << | arithmetic shift right and shift left |
| + and - | addition and subtraction |
| * and / | multiplication and division |
| +, -, !, ~, ++, and -- | unary plus, unary negation, logical not, bit complement, pre-increment, post-increment, pre-decrement, and post-decrement ++ and -- are not available in Expression Nodes. |
| ** | exponentiation |
| Note In versions of LabVIEW earlier than 6.0, the ^ operator represented exponentiation. The ^ operator now represents the bitwise exclusive or (XOR) operation. The new operator for exponentiation is **, for example, x**y. |
The assignment operator = is right associative (groups right to left), as is the exponentiation operator **. All other binary operators are left associative.
The numeric value of TRUE is 1, and FALSE is 0 for output. The logical value of 0 is FALSE, and any non-zero number is TRUE. The logical value of the conditional expression
<lexpr> ? <texpr>: <fexpr>
is <texpr> if the logical value of <lexpr> is TRUE and <fexpr> otherwise.
