Defined in header <type_traits>
template< class T >
struct is_floating_point;
(since C++11)

If T is a floating-point type (float, double, long double, including any cv-qualified variants), provides the member constant value equal true. For any other type, value is false.

Member constants

value
[static]
true if T is a floating-point type , false otherwise
(public static member constant)

Member functions

operator bool
converts the object to bool, returns value
(public member function)

Member types

Type Definition
value_type bool
type std::integral_constant<bool, value>

[edit] Possible implementation

[edit] Example

#include <iostream>
#include <type_traits>
 
class A {};
 
int main() 
{
    std::cout << std::boolalpha;
    std::cout << std::is_floating_point<A>::value << '\n';
    std::cout << std::is_floating_point<float>::value << '\n';
    std::cout << std::is_floating_point<int>::value << '\n';
}

Output:

false
true
false
