使用 std::to_string() 将 double 转换为字符串时，有什么方法可以设置结果的精度？
最佳答案
没有。
Returns: Each function returns a string object holding the character representation of the value of its argument that would be generated by calling
sprintf(buf, fmt, val)with a format specifier of"%d","%u","%ld","%lu","%lld","%llu","%f","%f", or"%Lf", respectively, where buf designates an internal character buffer of sufficient size.
