Setprecision and setiosflags in C++

In the example that i took from the deitels C book there is a statement in the code which is shown in below can you explain what does this codes means
thank you

Code:

---

using std::setprecision;
using std::setiosflags;

cout << setiosflags(ios::fixed | ios::showpoint);
cout << setprecision(1);

---

Yes, but it would be somewhat easier if you made use of existing material that explains them: cppreference.com entry list on Input/output manipulators
