      [editar]Possível implementação

      template<class R1, class R2 >struct ratio_not_equal :std::integral_constant<bool, !std::ratio_equal<R1, R2>>{};

      [editar]Exemplo

      #include <iostream>#include <ratio>   int main(){if(std::ratio_not_equal<std::ratio<2,3>, std::ratio<1,3>>::value){std::cout<<"2/3 != 1/3\n";}else{std::cout<<"2/3 == 1/3\n";}}

      Saída: 

      2/3 != 1/3
