What is BCD full form?
BCD stands for Binary Coded Decimal. Binary coded decimal (BCD) is a system of writing numerals that assigns a four-digit binary code to each digit 0 through 9 in a decimal (base-10) numeral. The four-bit BCD code for any particular single base-10 digit is its representation in binary notation, as follows: 0 = 0000. BCD is commonly used in digital systems that require precise decimal arithmetic, such as calculators, cash registers, and accounting systems. It is also used in real-time clock circuits and measurement systems.
