c++ std string to float

#include <iostream>
#include <string>

int main() {
    std::string str = "123.4567";

    // convert string to float
    float num_float = std::stof(str);

    // convert string to double
    double num_double = std::stod(str);

   std:: cout<< "num_float = " << num_float << std::endl;
   std:: cout<< "num_double = " << num_double << std::endl;

    return 0;
}

                                    std::string num = &quot;0.6&quot;;
double temp = ::atof(num.c_str());

std::cout &lt;&lt; temp &lt;&lt; std::endl;
// Output: 0.6
