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.
