Thread: Program BCD to Hex and Hex to BCD

Your best bet is:
If BCD -> Hex : Convert BCD to Decimal, then that to Hex
If Hex -> BCD : Convert Hex to Decimal, then that to BCD

Can't you just do the conversions directly by the use of lookup tables?

I don't think so, because here's an example:

12(10) = 1100(2) = C(16) = 00010010(BCD)

If you wanted just to print it though, yes it would be the easiest thing to do.
