This is true even when comparing with itself (``NAN == NAN`` returns ``false`` and ``NAN != NAN`` returns ``true``). Due to this, you must use :ref:`@GlobalScope.is_nan()<class_@GlobalScope_method_is_nan>` to check whether a number is equal to :ref:`NAN<class_@GDScript_constant_NAN>`.
 
 \ **Warning:** "Not a Number" is only a concept with floating-point numbers, and has no equivalent for integers. Dividing an integer ``0`` by ``0`` will not result in :ref:`NAN<class_@GDScript_constant_NAN>` and will result in a run-time error instead.
