How to convert float to string in C++?

In C++, you can convert a float type to a string type using the std::to_string() function, as shown below:

#include <iostream>
#include <string>

int main() {
    float number = 3.14f;
    std::string str = std::to_string(number);
    
    std::cout << "Float number: " << number << std::endl;
    std::cout << "String representation: " << str << std::endl;
    
    return 0;
}

When running the program, the output is:

Float number: 3.14
String representation: 3.140000
