I'm trying to make a basic calculator written as a turing machine. I want it so I can input something like "44+10" then it will return and output of "54", "44*10" returning "440", "44/10" returning "4" (I don't need the remainder), and "44-10" returning "34". The numbers are allowed to be any size.
My first thought was to convert these numbers into binary then do the math as binary operations then convert it back to decimal again. Or I could work in decimal the whole way.
I have these made so far:
decimal to bcd converter
shift left operation
shift right operation
and I'm using jflap to make these. Anyone have any pointers on a good approach to make this? Working in binary a good idea? Has this already been done before? If so where can I see it?
