BCD Arithmetic

Implementation of arithmetic in binary-coded decimal (BCD).

Features

• 8 decimal digits.
• Addition.
• Subtraction.
• Multiplication.
• Division.

Usage

#include <iostream>
#include <format>

#include "BCD.h"

int main() {
    BCD a{ "116.45" };
    BCD b{ "37374.042" };

    std::cout << std::format("{} + {} = {}\n", a.to_string(), b.to_string(), (a + b).to_string());
    std::cout << std::format("{} - {} = {}\n", a.to_string(), b.to_string(), (a - b).to_string());
    std::cout << std::format("{} * {} = {}\n", a.to_string(), b.to_string(), (a * b).to_string());
    std::cout << std::format("{} / {} = {}\n", a.to_string(), b.to_string(), (a / b).to_string());

    return 0;
}
