Returns [code]true[/code] if [param x] is a NaN ("Not a Number" or invalid) value.
Returns [code]true[/code] if [param x] is a NaN ("Not a Number" or invalid) value. This method is needed as [constant @GDScript.NAN] is not equal to itself, which means [code]x == NAN[/code] can't be used to check whether a value is a NaN.
