I think it is reasonable to capture to_string() as a standard, extrinsic function template that returns a std::string from T. Each T must supply a specialization that does the right thing, of course,
I was expecting it to be a wrapper around lexical_cast.
stoi(), stoll(), stof(), stod() seem less useful, though providing a portable C++03 implementation wouldn't be bad.
Don't those functions require std::string as input? I'd be nice to have generic variants.
I wouldn't use any of these. The functions I wrote for this purpose take either a const char*, or a const char** if you want the iterator advanced. For int-to-string, you pass begin and end pointers, and the digits are written from right to left, padding with zeroes or truncating the numeral as necessary. A function taking just the int and returning a string is a trivial wrapper around this one. Josh
