double is shown as float in size (newbie)

Hello there codeguru gurus...
here is my code:

PHP Code:

---

#include <iostream>
using namespace std;

double sqrtOfTwo(int counter)
{
    if (counter==0)
        return 0;
    else 
    {
        counter--;
        return 1.0/(2.0+sqrtOfTwo(counter));
    }    
}

int main()
{
    cout << rec(10); // doesn't really matter what number comes here
    return 0;
} 


---

when i run this code the output will be : 0.414214 , which is shorter than what i'd expect to receive, having declared this function as a double, not as a float. this may be something i simply do not understand in the way variable types work. either way, i'd really appreciate details regarding this issue.

This is just because of the default ostream outputprecision.
try like this

Code:

---

#include <iostream>
#include <iomanip>
using namespace std;


double sqrtOfTwo(int counter) {
    if (counter==0)
        return 0;
    else  {
        counter--;
        return 1.0/(2.0+sqrtOfTwo(counter));
    }
}

int main() {
    cout << setprecision(12) << sqrtOfTwo(10); // doesn't really matter what number comes here
    return 0;
}

thanks!
that was quick...
