The use of parentheses, even those not required to enforce a desired order of operations, can clarify the intent behind a piece of code. But redundant pairs of parentheses could be misleading, and should be removed.

Noncompliant Code Example

x = (y / 2 + 1)  # Compliant even if the parenthesis are ignored by the compiler

if a && ((x+y > 0))  # Noncompliant
  # ...
end

return ((x + 1)) # Noncompliant

Compliant Solution

x = (y / 2 + 1)

if a && (x+y > 0)
  # ...
end

return (x + 1)
