Fun Fact
Binary Coded Decimal is still widely used in financial and calculator systems because it avoids rounding errors that can occur when pure binary representations are used for decimal fractions.
Historical Context
BCD originated in the earliest days of computing when hardware displays and punch-card machines needed a simple way to represent decimal digits using binary signals. Instead of converting entire numbers to binary, each digit was encoded separately as a 4-bit value. This method became popular in early mainframes, digital clocks, and microcontrollers, and it remains important today in embedded systems, banking applications, and digital electronics education.
