Converting Double to String in C++

Question

I am having some issues trying to convert a double to C++ string. Here is my code

std::string doubleToString(double val)
{
    std::ostringstream out;
    ou         


        

Answer 1

#include 
using namespace std;
// ...
out << fixed << val;
// ...

You might also consider using setprecision to set the number of decimal digits:

out << fixed << setprecision(2) << val;
