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
DECLARE @x INT = (@y / 2 + 1); -- Compliant even if the parentheses are ignored
IF (@x > 0) AND ((@x+@y > 0)) -- Noncompliant
BEGIN
-- ...
END
Compliant solution
DECLARE @x INT = (@y / 2 + 1);
IF (@x > 0) AND (@x+@y > 0)
BEGIN
-- ...
END
