Force positive representation in GF
I work with arbitrary finite field
q power of prime. I've been looking around for some function, which would force, that any element is printed as a positive natural number. i.e. in
-2 is printed as
3 etc. Is that possible in an easy way? I need to achieve that for arbitraty
q. I've been thinking about writing some own function, but it seems intractable for me at the moment.
