using namespace std;

int main() {
    double h;
    while (cin >> h) {
        double sum = 0;;
        for (int i = 1; i <= 5; i++) {
            sum += h;
            h /= 2;
            if (i == 5) {
                cout << setprecision(6) << sum << endl <<
              setprecision(6) << h << endl;
            }
            sum += h;
        }
    }
}
