Binary-Coded Decimal (BCD) is a class of binary encodings of decimal numbers where each decimal digit is represented by a fixed number of binary bits. Decimal to BCD conversion is the process of converting a decimal number to its equivalent Binary-Coded Decimal representation. This involves converting each decimal digit to its 4-bit binary representation. For example, to convert the decimal number 123 to BCD: Decimal digits: 1 2 3, Binary representation: 0001 0010 0011 (in BCD, each decimal digit is represented by a 4-bit binary number). So, the BCD representation of 123 is 0001 0010 0011. View Solution Guide
