      F.A.Q
        Q: buT cAN iT rUn dOOm?
        A: It can't really "run" anything, its a number.
      
        Q: Is it fast?
        A: Define "fast". If you mean "faster than copying Euclid by hand", then yes, dramatically.
    
        Q: Why did you make this?
        A: I wanted arbitrary precision arithmetic, but I also wanted to feel something.
    
    I can relate. Expecially the 3rd one.

      Haha thank you! I'm glad to hear!

    Cool. I just learned of compass and straight edge calculations from this video on doubling a cube https://www.youtube.com/watch?v=96LbF8nn05c from Ben Syversen's channel a couple of months ago

    Thanks for posting, means a lot! :) I'd be happy to know how you stumbled upon it

      > CasNum (Compass and straightedge Number) is a library that implements arbitrary precision arithmetic using compass and straightedge constructions. Arbitrary precision arithmetic, now with 100% more Euclid. Featuring a functional modified Game Boy emulator where every ALU opcode is implemented entirely through geometric constructions.

      Awesome :D

    This is so nice!!

    I'm wondering how hard would it be to extend it to include the whole game state plus all the ROM into the plane at the same time, and have it compute the next step from that!

      That's a good question :)

      I was wondering about this myself, it feels and probably is possible, and I have some ideas on how to do it. Though, on the one hand it would be cool if the entire GB was emulated using compass-and-straightedge, but OTOH, it would be less "pure" and a little more "forced" than just simulating the ALU, if you get what I mean.

      One idea I had is trying to draw the graphics of the game using compass-and-straightedge constructions (i.e., using circles and lines to draw approximately the GB graphics)

    Tried to use it to solve a quintic equation and it didn’t work :(

    Was Claude used?

      The only part of the code that was written by AI is the graphics window visualizing the constructions (i.e., the points, lines and circles) and I used codex

    I have no idea what is going on here...
