Changing Evaluation Order of Operators
From InterBase
Go Up to Determining Precedence of Operators
To change the evaluation order of operations in an expression, use parentheses to group operations that should be evaluated as a unit, or that should derive a single value for use in other operations. For example, without parenthetical grouping, 3 + 2 * 6 evaluates to 15. To cause the addition to be performed before the multiplication, use parentheses:
(3 + 2) * 6 = 30
Tip:
Always use parentheses to group operations in complex expressions, even when default order of evaluation is desired. Explicitly grouped expressions are easier to understand and debug.
