Lénárd already mentioned Boost.Multiprecision (
https://www.boost.org/doc/libs/1_76_0/libs/multiprecision/doc/html/index.html).
There are other big integer libraries and there have been other proposals
including `integer`, proposed in (N4038) and mentioned in (
https://wg21.link/p1890r0).

Using `std::string` to represent the number means that calculations are
less efficient than they could be. It also means that they cannot be used
in arithmetic expressions, because adding strings together appends them.

Cheers,
John
