You look and see whether it is signed!!!
If you insist on not knowing it is harder.
It is even harder if you insist on handcuffing yourself
and typing with your nose :-)
In a real situation, you know what type you are dealing with
and the section of code that has the enum type can export the
corresponding integral type and indeed the routine for doing
the conversion!
