The use of parentheses, even those not required to enforce a desired order of operations, can clarify the intent behind a piece of code. However,
redundant pairs of parentheses could be misleading and should be removed.
Noncompliant code example
x := (y / 2 + 1); -- Compliant even if the parentheses are ignored
IF (x > 0) AND ((x+y > 0)) THEN -- Noncompliant
-- ...
END IF;
Compliant solution
x := (y / 2 + 1);
IF (x > 0) AND (x+y > 0) THEN
-- ...
END IF;
