#include <iostream>
  
using namespace std;
  
int main()
{
  
    // Initializing the floating values
    double n1 = 10;
    double n2 = 20.0;
  
    cout.precision(5);
  
    // Using noshowpoint()
    cout << "noshowpoint flag: "
         << noshowpoint
         << n1 << endl
         << n2 << endl;
  
    return 0;
