C++：将双精度数转换为字符串的最佳方法是什么

cpp
#include <IOStream>
#include <sstream>
int mAIn() {
    double number = 3.1415926;
    
    std::ostringstream oss;
    oss << number;</p>    std::string str = oss.str();
    
    std::cout << "转换后的字符串为：" << str << std::endl;</p>    
    return 0;
}

cpp
#include <IOStream>
#include <string>
int mAIn() {
    double number = 3.1415926;
    
    std::string str = std::to_string(number);
    
    std::cout << "转换后的字符串为：" << str << std::endl;</p>    
    return 0;
}
