using std::ios;

int main()
{
   double x = .001234567, y = 1.946e9;

   cout << "Displayed in default format:\n" << x << '\t' << y << '\n';

   cout.setf( ios::scientific, ios::floatfield );
   cout << "Displayed in scientific format:\n" << x << '\t' << y << '\n';

   cout.unsetf( ios::scientific );
   cout << "Displayed in default format after unsetf:\n" << x << '\t' << y << '\n';
