BeeNum is an arbitrary-precision arithmetic library.

Integers:

Bint a = "372542872459";
Bint b = "-29351077";
Bint c = "-SomeNumbersAreHere::62";                // base 62
Bint d = "-9:10:79💯16:3:35:72:76:15:11::101";  // base 101

a *= b;

std::cout << "a = " << a << std::endl;
std::cout << "a bin = " << a.bin() << std::endl;
std::cout << "a hex = " << a.hex() << std::endl;
std::cout << "a oct = " << a.oct() << std::endl;
std::cout << "a b12 = " << a.base(12) << std::endl;
std::cout << "a b16 = " << a.base(16) << std::endl;
std::cout << "a b62 = " << a.base(62) << std::endl;
std::cout << "a b100 = " << a.base(100) << std::endl;
std::cout << "a b101 = " << a.base(101) << std::endl;
std::cout << "-a hex= " << (-a).hex() << std::endl;

a = Math::fib(2344); // fibonnaci
std::cout << "a = " << a << std::endl;
a = Math::fact(2344); // factorial
std::cout << "a = " << a << std::endl;
