Since the logical and bitwise operators have a lower precedence than other arithmetic and relational operators, any bitwise operations should be enclosed in parentheses to ensure accurate execution. Note that if Not someStr?.Contains("some string") or any other value that evaluates as Boolean? has...
Precedence Rules When expressions contain operators from more than one category, they are evaluated according to the following rules: The arithmetic and concatenation operators have the order of precedence described in the following section, and all have greater precedence than the comparison, logical, ...

The same precedence rule holds true for the&∧||operators. Overriding Default Precedence The defaultprecedence can be overridden using parentheses, as shown in this example: A = [3 9 5]; B = [2 1 5]; C = A./B.^2 C = 0.7500 9.0000 0.2000 C = (A./B).^2 C = 2.2500 81.0000 ...
Use parentheses to override the defined precedence of the operators in an expression. Everything within parentheses is evaluated to yield a single value. That value can be used by any operator outside those parentheses. For example, in the expression used in the followingSETstatement, the multipli...
However, the precedence and associativity rules only tell us how operators and operands are grouped and the order in which value computation will occur. They do not tell us the order in which the operands or subexpressions are evaluated. The compiler is free to evaluate operands a, b, c, or...
