    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?

    source

    • yardy_sardley@lemmy.ca ⁨4⁩ ⁨weeks⁩ ago

      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?

  It also has a max of 31 days possible. Which has… implications.

    Among many other duties I manage the safety and claims database for an outsourced industrial cleaning company and let me tell you, some of the plants my company works struggle to make it a week without an accident, meanwhile some will go years without an accident. We also have one plant which had its last accident during the Bush Administration. Its absolutely wild how much safety can vary from one industrial facility to another

        This is actually how chromatography works. The mobile phase is 0.1% formic acid and 0.3% blood of the innocent.

  Unless it’s a signed integer, then it’s -1 and they’re expecting something…

    A 5 bit long signed integer? What kind of weird system you using ? :p

      Two’s complement

      source
    • phoenixz@lemmy.ca ⁨2⁩ ⁨weeks⁩ ago

      Because a 5 bit unsigned integer is so much better? :p

  • computergeek125@lemmy.world ⁨4⁩ ⁨weeks⁩ ago

    Only if you’re using a sign bit rather than two’s compliment (a sign bit allows for two representations of 0)

  Or 11 in hexadecimal

  • scholar@lemmy.world ⁨4⁩ ⁨weeks⁩ ago

    B is 11 in hex though?

    • deadcade@lemmy.deadca.de ⁨4⁩ ⁨weeks⁩ ago

      As in, 0x11 is 17 in decimal.
