is_arithmetic Class

Tests if type is arithmetic.

template<class Ty>
    struct is_arithmetic;

Parameters

• Ty
  The type to query.

Remarks

An instance of the type predicate holds true if the type Ty is an arithmetic type, that is, an integral type or a floating point type, or a cv-qualified form of one of them, otherwise it holds false.

Example

 

// std_tr1__type_traits__is_arithmetic.cpp 
// compile with: /EHsc 
#include <type_traits> 
#include <iostream> 
 
struct trivial 
    { 
    int val; 
    }; 
 
int main() 
    { 
    std::cout << "is_arithmetic<trivial> == " << std::boolalpha 
        << std::tr1::is_arithmetic<trivial>::value << std::endl; 
    std::cout << "is_arithmetic<int> == " << std::boolalpha 
        << std::tr1::is_arithmetic<int>::value << std::endl; 
    std::cout << "is_arithmetic<float> == " << std::boolalpha 
        << std::tr1::is_arithmetic<float>::value << std::endl; 
 
    return (0); 
    } 
 

is_arithmetic<trivial> == false is_arithmetic<int> == true is_arithmetic<float> == true
