Hi there, I need a way to convert a float to a string. I'm using C++ with Vis Stud 2005, and am using the MFC. It's for a calculator, so the size will need to be limited. A dot will always be the decimal seperator. Thanks very much

#include <sstream>ostringstream buffer;float f = 4.5;buffer << f;string str = buffer.str();
