static const bool is_bounded;		(until C++11)
static constexpr bool is_bounded;		(since C++11)

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.
