static const bool is_bounded
 (fino al c++11)
static constexpr bool is_bounded
 (dal C++11)
Il valore di std::numeric_limits<T>::is_bounded è true per tutti i tipi aritmetici T che rappresentano un insieme finito di valori. Mentre tutti i tipi fondamentali sono limitati, questa costante sarebbe false in una specializzazione di std::numeric_limits per una libreria fornita tipo arbitrario precisione aritmetica
Original:
The value of std::numeric_limits<T>::is_bounded is true for all arithmetic types T that represent a finite set of values. While all fundamental types are bounded, this constant would be false in a specialization of std::numeric_limits for a library-provided arbitrary precision arithmetic type
