Does any1 have a converter for binary to normal numbers?

i was going to redesign a past project with some of the newer elements but id like to finish the project with a converter

it would only need to convert 0-9

yea...not entirely sure how to work all of the parts in that but this is what i wanted to use it on



i basically wanted to have it so it could scan the barcodes and actually tell what value it contained

EDIT: rly EXACTLY what i need is a sort of revers rom so that a combination of inputs results in a single output

prefferably changeable tho not required
