To convert the given decimal number to XS3, I have to add 3 to each individual number and convert that number into BCD. If the given decimal number is 12 then adding 3 to each gives me 45 and the equivalent BCD is 0100 0101.
So, whats the XS-3 for 29? My calculations:
Adding 3 to each, i get 5 12. I knew from my book that I shouldn't take the carry into next column. Now, when I have to convert it to BCD, it converts to 0101 00010010. I converted 12 to its BCD (1 to binary and 2 to binary). But my text book is telling me that the answer is 0101 1100. 12 is converted to binary instead of BCD.
