Using ostringstream to convert float to string in C++ In this method we use 0stringstream to pass a float number to the buffer and then convert it into a string by using the str() method. setprecision(int n) function is also used with fixed to provide precision to floating numbers correct...
So, in reality, in order to work appropriately, you must always avoid this mix of data types. How? Defining your own "polymorphic" STL string data type:prettyprint 复制 typedef std::basic_string<TCHAR> tstring; Just like that. Then you would re-write the above as:...
