Can I just point out that the multiprecision lib will do a 12-bit int type
if that's what you want:
typedef number<cpp_int<12, 12, unsigned_magnitude, unchecked, void> >
Of course the signed version is signed-magnitude not 2's complement....
BTW, it may well also be worth investigating using multiprecision::number as
the front end for these types?
Now I'll go back to lurking ;-) John.
