The order of precedence controls the order in which operators in an expression are evaluated. The order of precedence is as follows:
Unary +, Unary - ^ *, / \ MOD +, - & EQ, NEQ, LT, LTE, GT, GTE, CONTAINS, DOES NOT CONTAIN NOT AND OR XOR EQV IMP
To enforce a non-standard order of evaluation, you must parenthesize expressions. For example:
You can nest parenthesized expressions. When in doubt about the order in which operators in an expression will be evaluated, use parentheses to force the order of evaluation.
