5.6.4.Normal (default) mode; only show 5 digits, including both sides of decimal point

#include <iostream>

#include <iomanip>

#include <string>



using namespace std;



int main( ) {



   ios_base::fmtflags flags = cout.flags( );



   double pi = 3.14285714;



   cout << "pi = " << setprecision(5) << pi << '\n';



   cout.flags(flags);

}

pi = 3.1429
