In a theoretical sense, yes -- but I doubt that that matters in
practice.  In practice, I think, the cases where one wants hexadecimal
are cases where there is a word width.

Would you tell me about some of the cases where you wanted hexadecimal
output and you wanted negative numbers to use a minus sign?

I ask because I am skeptical that such cases exist.
