template <class T>
struct is_fundamental : public true_type-or-false_type
{};
Inherits: If T is a (possibly cv-qualified) fundamental type then inherits from true_type, otherwise inherits from false_type. Fundamental types include integral, floating point and void types (see also is_integral, is_floating_point and is_void)
C++ Standard Reference: 3.9.1.

.
is_fundamental<double const>::type
is the typetrue_type
.
is_fundamental<void>::value
is an integral constant expression that evaluates to true.
is_fundamental<T>::value_type
is the typebool
.
