C++ output precision > 6 places?

hum ... using double does not make it display .000000003 ... i remember there was a iostream parameter you could change that changed the defaulted precision level? any ideas?

Here you go.

// setprecision example
#include <iostream>
#include <iomanip>
using namespace std;

int main () {
double f =3.14159;
cout << setprecision (5) << f << endl;
cout << setprecision (9) << f << endl;
return 0;
}

Use iomanip and setprecision.

 

[MacBaine]

You may have to include a

setiosflags<setios:: float || setios::fixed>

And then the setprecisions() should work.
