### is_floating_point

    template <class T>
    struct is_floating_point : public true_type-or-false_type {};

Inherits: If T is a (possibly cv-qualified) floating point type then inherits from true_type, otherwise inherits from false_type.

C++ Standard Reference: 3.9.1p8.

Header: `#include <boost/type_traits/is_floating_point.hpp>` or `#include <boost/type_traits.hpp>`

Examples:

> `is_floating_point<float>` inherits from `true_type`.

> `is_floating_point<double>::type` is the type `true_type`.

> `is_floating_point<long double>::value` is an integral constant expression that evaluates to true.

> `is_floating_point<T>::value_type` is the type `bool`.
