Fun Fact
Early electronic calculators and financial systems used BCD instead of pure binary because it minimized rounding errors in decimal arithmetic - something that remains relevant in financial computing even today.
Historical Context
Binary Coded Decimal was widely adopted in early computing systems, including IBM mainframes, because it allowed precise decimal representation for business and financial calculations. Hexadecimal later became popular in computing due to its compact mapping to binary, simplifying memory addressing and low-level programming. This converter bridges those two historical number systems in a modern, privacy-first web environment.
