int, float string data type conversion

Easy to learn, use programming

int turn string

int infor2 = (int)readdata[i];//int数据
CString info2；

info2.Format(_T("%d"), infor2);

float switch string

float num = (float)readdata[i];//float数据

ostringstream num_float;

string str(num_float.str());

Similarly two methods, a method can be selected according to the actual situation, for the same reason double type.
