Hey, so I built an 8-bit calculator in minecraft. This has been a project of mine for quite some time, and I finally got it finished.

Using only redstone, repeaters, torches, comparators, and pistons, this calculator can add, subtract, multiply, or divide two 8-bit numbers (0-255). Division will give you two digits past the decimal point of accuracy.

How the hell is this possible: (gibberish warning)
For the user's input, I used a binary encoder to convert each digit to BCD. The BCD is then sent to the display, and to two 8-bit BCD to binary converters. The operation the user picks determines where they are sent to next. Addition sends them to the binary adder, subtraction sends them to the binary subtractor, etc. Once the calculation is done, the binary result is sent to a 16-bit binary to BCD converter. Finally, each BCD digit is decoded for its seven segment display.

Dude, this thing and that REDFIVE calculator inspired me to create a calculator like this one, and it ended up being faster than this one and almost as fast as REDFIVE.

If you type in 0 divided by 0 it says "no"

Nice touch!

Does the map work on 1.12.2? If not, is there a way to convert it?
