BCD takes advantage of the fact that any one decimal numeral can be represented by a four-bit pattern. The most obvious way of encoding digits is Natural BCD (NBCD), where each decimal digit is represented by its corresponding four-bit binary value, as shown in the following table. This is also called "8421" encoding. This scheme can also be referred to as Simple Binary-Coded Decimal (SBCD) or BCD 8421, and i…
