Include: #include "tools/is_arithmetic.hpp"

template <typename T>
struct is_arithmetic {
  static constexpr bool value;
};

template <typename T>
inline constexpr bool is_arithmetic_v = is_arithmetic<T>::value;

tools::is_arithmetic_v<T> is equivalent to std::is_arithmetic_v<T> || std::is_same_v<std::remove_cv_t<T>, tools::int128_t> || std::is_same_v<std::remove_cv_t<T>, tools::uint128_t>. When using libstdc++ with -std=c++... option, std::is_arithmetic_v<tools::int128_t> and std::is_arithmetic_v<tools::uint128_t> are treated as false, but with tools::is_arithmetic, they can be treated as true.
