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

Standard specializations

T	value of std::numeric_limits<T>::is_bounded
/* non-specialized */	false
bool	true
char	true
signed char	true
unsigned char	true
wchar_t	true
char16_t	true
char32_t	true
short	true
unsigned short	true
int	true
unsigned int	true
long	true
unsigned long	true
