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.
