I’m going to make a computer in Minecraft. I understand how to build a computer where it can make binary operations but I want the outputs to be displayed as standard integer numbers. How you “convert” the binaries into standard digits? Is there any chart for that? And the digits will be shown like in old calculators; with 7 lines.

In electronics, what you need is called a “binary to binary coded decimal” converter. “Binary coded decimal” is the set of bits needed to produce a number on a 7 segment display. Here’s a PDF describing how one of these chips works. Page 3 of the PDF shows the truth table needed to do the conversion as well as a picture of all of the NAND gates that implement it in hardware. You can use the truth table to build the set of boolean expressions needed in your program.
