    For anyone who doesn’t want to do the conversion, that’s 17 days.

        Mmm yes. 5 bit two’s complement.

        I shouldn’t make fun of it we’ve definitly made some ISA that weird.

        what’s the general rule for translating negatives from binary? did you just do like 17 - 2 • (-1) or something?

          I used what known as 2’s compliment. Take the complement (flip all the bits - here that would give you 01110 which is 14) then add 1.

            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.

              In C, the not operator is ! and the compliment operator is ~

          As in, 0x11 is 17 in decimal.
