is_arithmetic Class

Tests if type is arithmetic.

Syntax

template <classTy> structis_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>structtrivial { int val; }; intmain() { 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
