Homonym: BCD (Binary)
BCD, or Binary-Coded Decimal, is a method of representing decimal numbers in a binary format. In BCD, each digit of a decimal number is represented by its own four-bit binary equivalent. For example, the decimal number 25 is represented in BCD as 0010 0101, where 0010 represents the digit 2 and 0101 represents the digit 5.
This encoding system is commonly used in digital systems, such as calculators and digital clocks, where precise decimal representation is important. BCD allows for easier conversion between binary and decimal systems, making it useful in applications that require human-readable output, like digital displays.
