Confusion -- Return value ... (int, float)

Hi,

The mission parameters says the return value should be the difference between the min and max values. The "(int, float)" confused me because, as with most missions, that would imply the return value is expecting both and int and a float, as a tuple of the form (int(diff), float(diff)). It's not so clear that the expected returned value is a single value, as either and int or a float. (I simply made it always return a full float, thus no loss of precision in any conversions.)
