    Template:cpp/types/sidebar Template:ddcl list begin

    Defined in header <type_traits> 
    template< class T >
struct is_arithmetic;

    Template:mark c++11 feature Template:ddcl list end If T is an arithmetic type (that is, an integral type or a floating-point type), provides the member constant value equal Template:cpp. For any other type, value is Template:cpp.

    Inherited from std::integral_constant

    Member constants

    value
    [static]
    		 true if T is an arithmetic type , false otherwise
    (public static member constant)

    Member functions

    operator bool
    		 converts the object to bool, returns value
    (public member function)
    operator()
    (C++14)
    		 returns value
    (public member function)

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

    Notes

    Arithmetic types are the types for which the built-in arithmetic operators (+, -, *, /) are defined (possibly in combination with the usual arithmetic conversions)

    Specializations of Template:cpp are provided for all arithmetic types.

    Equivalent definition

    Template:eq fun cpp

    Example

    Template:example cpp
