== Exceptions
|
|
|
|
* This rule ignores ``++*++``, ``+``, and ``++=++``.
|
|
* The specific case of testing a floating point value against itself is a valid test for ``++NaN++`` and is therefore ignored.
|
|
* Similarly, left-shifting 1 onto 1 is common in the construction of bit masks, and is ignored.
