The C Style way is probably to use sprintf:

#include <stdio.h>

float f;
char str[50];
sprintf(str,"%f",f);

then str contains the string rep.

or in C++ style, try:

#include <sstream>
#include <string>
using namespace std;

float f;
ostringstream os;
os << f;
string str = os.str();

both should be portable.
