utx::uxmax is the maximum unsigned integral class type, utx::uxmax is equivalent to utx::ux64 in most of the cases, utx::uxmax and utx::ux64 have the same bit size, and both of them are unsigned integral type, however utx::uxmax and utx::ux64 are two different types.
utx::uxmax - utx::umax, the class type of utx::umax.
#include <utxcpp/core.hpp> int main() { constexpr utx::uxmax x = 13423; utx::print(x); }
