I have to transfer binary to decimal and back. I'm having problems figuring out how to word the coding for sm, 1's and 2's complement and excess notation

mathmate · Answer

I would put the binary and decimal representations as string, and then you can parse each string character by character.
If you have difficulty understanding ones and twos complements, read link given above.
