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. 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() { std::ratio_not_equal_v<std::ratio<2, 3>, std::ratio<1, 3>> ? std::cout << "2/3 != 1/3\n" : std::cout << "2/3 == 1/3\n"; } Output: 2/3 != 1/3 See also ratio_equal compares two ratio objects for equality at compile-time (C++11) (class template) http://cppreference.com 2024.06.10 std::ratio_not_equal(3)
