std::ratio_not_equal(3) C++ Standard Libary std::ratio_not_equal(3) NAME std::ratio_not_equal - std::ratio_not_equal Synopsis Defined in header <ratio> template< class R1, class R2 > struct ratio_not_equal : std::integral_constant<bool, /* see below (since C++11) */> { }; If the ratios R1 and R2 are not equal, provides the member constant value equal true. Otherwise, value is false. Helper variable template template< class R1, class R2 > inline constexpr bool ratio_not_equal_v = ratio_not_equal<R1, (since C++17) R2>::value; Inherited from std::integral_constant Member constants value true if R1::num != R2::num || R1::den != R2::den , false otherwise [static] (public static member constant) Member functions operator bool converts the object to bool, returns value (public member function) operator() returns value (C++14) (public member function) Member types Type Definition value_type bool type std::integral_constant<bool, value> Possible implementation template< class R1, class R2 > struct ratio_not_equal : std::integral_constant < bool, !std::ratio_equal<R1, R2> > {}; Example // Run this code #include <iostream> #include <ratio> int main() { if(std::ratio_not_equal<std::ratio<2,3>, std::ratio<1,3>>::value) { std::cout << "2/3 != 1/3\n"; } else { std::cout << "2/3 == 1/3\n"; } } Output: 2/3 != 1/3 See also http://cppreference.com 2022.07.31 std::ratio_not_equal(3)
