Tests if type is arithmetic.
Syntax
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__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::is_arithmetic<trivial>::value << std::endl;
std::cout << "is_arithmetic<int> == " << std::boolalpha
<< std::is_arithmetic<int>::value << std::endl;
std::cout << "is_arithmetic<float> == " << std::boolalpha
<< std::is_arithmetic<float>::value << std::endl;
return (0);
}
is_arithmetic<trivial> == false
is_arithmetic<int> == true
is_arithmetic<float> == true
