      Notas

      Na maioria das plataformas divisão por zero sempre armadilhas, e std::numeric_limits<T>::traps é true para todos os tipos inteiros que suportam o valor 0. A exceção é o bool tipo: embora a divisão por armadilhas false devido a promoção integral da bool para int, são as armadilhas zero-valorizado que int. Zero não é um valor de bool tipo.
      Original:
      On most platforms integer division by zero always traps, and std::numeric_limits<T>::traps is true for all integer types that support the value 0. The exception is the type bool: even though division by false traps due to integral promotion from bool to int, it is the zero-valued int that traps. Zero is not a value of type bool.

      Na maioria das plataformas, exceções de ponto flutuante pode ser ligado e desligado em tempo de execução (por exemplo feenableexcept() no Linux ou _controlfp no Windows), caso em que o valor de std::numeric_limits<T>::traps para tipos de ponto flutuante reflete o estado de ponto flutuante de instalação em armadilhas o tempo de inicialização do programa, que é false na maioria dos sistemas modernos. Uma excepção seria um DEC Alpha programa, onde é true se compilado sem -ieee.
      Original:
      On most platforms, floating-point exceptions may be turned on and off at run time (e.g. feenableexcept() on Linux or _controlfp on Windows), in which case the value of std::numeric_limits<T>::traps for floating-point types reflects the state of floating-point trapping facility at the time of program startup, which is false on most modern systems. An exception would be a DEC Alpha program, where it is true if compiled without -ieee.
