How to Convert a Float to a string
-
Hi i hav converted an integer to a string using the following method, CString str; int i; char TempBuffer[50]; _itoa(i,TempBuffer,10) str=TempBuffer; Now how can i convert a Float to a string . any can please tell mi the solution(easy if the soln is similar to the above) thanks

itoa is only between int and char. if you want float or double try dtostr / strtod And still better, if you are using CString, then use CString::Format CString szValue = ""; szValue.Format (_T("%f"), doubleVariable); This works with hexadecimal, int, binary... take a look in documentation.
Greetings. -------- M.D.V. If something has a solution... Why do we have to worry about?. If it has no solution... For what reason do we have to worry about? Help me to understand what I'm saying, and I'll explain it better to you ;)

CString t; t.Format("%f", floatVal);

the result from google search "c++ float to string" give this example...
int main() { char* str = new char[30]; float flt = 2.4567F; sprintf(str, "%.4g", flt ); cout< [Insert Witty Sig Here] -

Besides all those Old-School C-Ways of converting, there is the std::stringstream:
#include <strstream>
#include <iostream>const double pi = 3.14; //Feel free to a digits at will
std::string piString;int main(int argc, char * argv[])
{
std::stringstream stream;
stream << pi;
//put any number of formatters here
stream >> piString;std::cout << piString;
return system("pause");
}Also, boost::lexical_cast[^] comes to mind.
Though I speak with the tongues of men and of angels, and have not money, I am become as a sounding brass, or a tinkling cymbal.

Why are you using an intermediary variable? Convert
idirectly intostr.

You just as easily could have taken Google's second or third result and been much better off.
