+     * callback, it will inform the user and set HVAC temperature to the suggested value.
+     *
+     * Another example, an application receives 21 Celsius as the current temperature value by
+     * querying HVC_TEMPERATURE_SET. But the application wants to know what value is displayed on
+     * the car's UI in Fahrenheit.
+     * For this, the application sets the property to [21, (float)VehicleUnit:CELSIUS, 0, 0]. If
+     * the suggested value by the OEM for 21 Celsius is 70 Fahrenheit, then VHAL must generate a
+     * callback with property value [21, (float)VehicleUnit:CELSIUS, 21.0, 70.0].
