<p>
            For similar reasons continuous distributions with parameters like "degrees
            of freedom" that might appear to be integral, are treated as real
            values (and are promoted from integer to floating-point if necessary).
            In this case however, there are a small number of situations where non-integral
            degrees of freedom do have a genuine meaning.
