c++ integer->std::string conversion. Simple function?

std::string intToString(int i)
{
    std::stringstream ss;
    std::string s;
    ss << i;
    s = ss.str();

    return s;
}

template<class T>
std::string t_to_string(T i)
{
    std::stringstream ss;
    std::string s;
    ss << i;
    s = ss.str();

    return s;
}

std::string s = t_to_string(my_integer);

std::string s = boost::lexical_cast<std::string>(i);

try{
  std::string s = boost::lexical_cast<std::string>(i);
}catch(boost::bad_lexical_cast &){
 ...
}
