BEFORE DOWNLOADING MAP PLEASE READ 1ST PARAGRAPH
If you want to input a 1-digit number, e.g. 7, you MUST input it as 07. This machine is very large, and you may need render to be on far for the entire machine to be loaded, or you will have update issues. If this still doesn't work, you may need to download Optifine to increase your render. Please leave around a 1 second gap between each button press, or you may confuse the machine. The display will flicker after pressing equals as it calculates the answer, but if you wait a bit the correct answer should display.

This is a calculator that I have built in Minecraft. It is not fully functional at the moment, as the highest output you can get is 239. The only reason for the current limitation is the binary to 7-seg display decoder, as it takes ages to program the decoders. Once it is finished, the highest output will be around 3040, which I feel is fairly decent. Unfortunately, it is fairly slow, but I am working on replacing some repeaters in long buses with instant-wire, which will speed the machine up considerably. It can handle negative outputs as well, but not negative inputs.

If any bugs appear, and you are certain they are repeatable errors, do not hesitate to tell me, and I will address the problem as soon as possible.
