std::chrono...ration::zero(3) C++ Standard Libarystd::chrono...ration::zero(3) NAME std::chrono::duration::zero - std::chrono::duration::zero Synopsis static constexpr duration zero(); (until C++20) static constexpr duration zero() noexcept; (since C++20) Returns a zero-length duration. If the representation rep of the duration requires some other imple- mentation to return a zero-length duration, std::chrono::duration_values can be specialized to return the desired value. Parameters (none) Return value returns duration(std::chrono::duration_values<rep>::zero()) Example // Run this code #include <chrono> #include <ratio> int main() { static_assert((std::chrono::hours::zero() == std::chrono::nanosec- onds::zero()) && (std::chrono::duration<short, std::nano>::zero() == std::chrono::duration<int, std::deci>::zero()) && (std::chrono::duration<short, std::deca>::zero() == std::chrono::duration<long, std::exa>::zero()) && (std::chrono::duration<long, std::atto>::zero().count() == std::chrono::duration<float, std::exa>::zero().count())); } See also min returns the special duration value min [static] (public static member function) max returns the special duration value max [static] (public static member function) http://cppreference.com 2022.07.31 std::chrono...ration::zero(3)
