accuracy of four decimal spaces

Question

I've written this code
#include <iostream>
#include <cmath>
using namespace std;
int main() {
float disGh, disP, dGholi, dPoli;
double thGholi, thPoli;
cin >> dGholi >> thGholi;
cin >> dPoli >> thPoli;

disGh = dGholi / (2*(1-pow(0.5000,thGholi)));
disP = dPoli / (2*(1-pow(0.5000,thPoli)));

if (disGh > disP)
cout << "GHOLI WINS" << endl << disGh;
else if (disGh < disP)
cout << "PPOLI WINS" << endl << disP;
else
cout << "DRAW" << endl << disGh;
}

and it does what I want just fine, the problem is that for example if I put "14 3 15 2" in it, it gives POLI WINS
10
but I want it to say 10.0000
with 4 decimal spaces
I was wondering if there was a function that could do it

Answer 1

#include <iomanip>

cout << setprecision(6) << showpoint;
Put the line (above)... anywhere before you want it to take effect.
..please note.. they are modal .i.e. they stay in effect until you change them to something else.
