C++ (Cpp) hours::count Exemples

Exemple #1

Fichier : ceil.pass.cpp Projet : 32bitmicro/riscv-libcxx

int main()
{
//  7290000ms is 2 hours, 1 minute, and 30 seconds
    test(std::chrono::milliseconds( 7290000), std::chrono::hours( 3));
    test(std::chrono::milliseconds(-7290000), std::chrono::hours(-2));
    test(std::chrono::milliseconds( 7290000), std::chrono::minutes( 122));
    test(std::chrono::milliseconds(-7290000), std::chrono::minutes(-121));

    {
//  9000000ms is 2 hours and 30 minutes
    constexpr std::chrono::hours h1 = std::chrono::ceil<std::chrono::hours>(std::chrono::milliseconds(9000000));
    static_assert(h1.count() == 3, "");
    constexpr std::chrono::hours h2 = std::chrono::ceil<std::chrono::hours>(std::chrono::milliseconds(-9000000));
    static_assert(h2.count() == -2, "");
    }
}
