| Let's look at 159. The hundreds digit 1 is represented in binary by 0001. The tens digit 5 is represented in binary by 0101. The ones digit 9 is represented in binary by 1001. The entire number 159 in BCD is therefore: 000101011001. However 159 in binary is represented by 10011111. Again we need a way to convert this binary number 10011111 to its BCD equivalent 000101011001. To do this, we will use the Double Dabble algorithm. | Let's look at 159.
