You should never assume operator precedence. It varies between languages. Even if you know it, the people maintaining your code in the future might not know it. Or they they might not know that you know it. In the interests of readable code, always insert extra parentheses to make it clear what you are intending.
ie.
if ((value < lower_limit) || (value > upper_limit))
is more readable than
if (value < lower_limit || value > upper_limit)
Even though they compile to the same code
Just try writing the second form in Delphi/Pascal and you will come unstuck.
