Table for Binary Coded Decimal DECIMAL NUMBERBCD00000100012001030011401005010160110701118100091001In the BCD numbering system, the given decimal number is segregated into chunks of four bits for each decimal digit within the number. Each decimal digit is converted into its direct binary form (usually represented in 4-bits). For example: 1. Convert (123)10 in BCD From the truth table above, 1 -> 0001 2 -> 0010 3 -> 0011 thus, BCD becomes -> 0001 0010 0011 2. Convert (324)10 in BCD (324)10 -> 0011 0010 0100 (BCD) Again from the truth table above, 3 -> 0011 2 -> 0010 4 -> 0100 thus, BCD becomes -> 0011 0010 0100 This is how decimal numbers are converted to their equivalent BCDs. It is noticeable that the BCD is nothing more than a binary representation of each digit of a decimal number.It cannot be ignored that the BCD representation of the given decimal number uses extra bits, which makes it heavy-weighted.Related articles: Program to Convert BCD number into Decimal number BCD Adder in Digital Logic BCD to 7 Segment Decoder
