template <class T>
struct is_arithmetic : public true_type-or-false_type
{};
Inherits: If T is a (possibly cv-qualified) arithmetic type then inherits from true_type, otherwise inherits from false_type. Arithmetic types include integral and floating point types (see also is_integral and is_floating_point).
