/*将整数转化为二进制的string 输出*/ string convert(int num) { string res = ""; if (num == 0) return "0"; int val = num; num = abs(num); while (num) { res.insert(0, to_string(num % 2)); num /= 2; } if (val < 0) res.insert(0, "-"); return res; } 方法二:...
string to_string (unsignedlonglongval); string to_string (floatval); string to_string (doubleval); string to_string (longdoubleval); 2.string转换为数值类型 2.1使用函数模板+ istringstream stringstream在int或float类型转换为string类型的方法中已经介绍过, 这里也能用作将string类型转换为常用的数值类型。
