BCD (Binary-Coded Decimal)

Binary-Coded Decimal (BCD) is a way to represent decimal numbers using binary code. In BCD, each digit of a decimal number is individually converted to its four-digit binary equivalent. For example, the decimal number 34 is represented in BCD as 0011 0100 (where 0011 is the binary for 3 and 0100 is for 4). This method is useful in digital devices like calculators and digital clocks, allowing for easy conversion between binary and decimal formats, making it easier to read and process numeric data while maintaining accuracy in decimal representation.
