Because code that uses the output may rely on the facy that it should be
a valid number, since %d was used. If you want "nil" to come out of it,
i would recommend trying:

string.format("%s", tostring(novalue))

Which will work as expected for numbers as well (altough you'll get the
fraction part as well, which isn't what you'd get with %d)..
