I used what known as 2’s compliment. Take the complement (flip all the bits - here that would give you
01110which is 14) then add 1.swag_money@lemmy.world 4 weeks ago
thanks for the explanation! could you express it as a NOT operation plus one? like is that how it would be processed at a low level?

My low level is a tad rusty from when I learned the C side in school, but if I recall the not operator resolves as a single Boolean (0 or 1 in true C), whereas compliment comes back as however many bits you put in - a not operation per bit.
