Below is the code for a function returing a double value as string whose precision is 15(i.e. no. of digit after decimal should be 15)
Click here to see the execution on ide
#include <bits/stdc++.h>
using namespace std;
string doit(){
cout<<setprecision(15)<<fixed;
double val = 4444/21;
// want to return it as string
string ans = to_string(val);
return ans;
}
int main() {
string ans = doit();
cout<<ans;
return 0;
}output is
211.000000
I want the output to contain 15 digits after decimal and it should be returned by the function and not use print/cout statement inside the function.
