 Message        <Context> this argument to <function name> and
                conversion specifier "<incorrect conversion>" combine
                integer and floating-point types.  Behavior can be
                unpredictable.

 Description    The compiler has detected an output conversion
                specifier whose data type does not match its
                corresponding argument in a way that will cause
                unpredictable behavior.

 User Action    Modify either the argument or the conversion
                specifier so that they match.
