As was mentioned in `[boost] to_string(v)` 1) Functions to_string and to_wstring are part of the upcoming C++0x standard.

Some users would like to use a shorter form.
Is there interest in stoi, stoll, stof, to_string, to_wstring, to_u16string, stod and other functions for char, wchar_t, char16_t and char32_t conversions? Shall I add them to lexical_cast library, or as a separate conversion library?
Fast implementations of these things are already available from Spirit, do you plan on reusing them?
to_string is defined in terms of sprintf [1], which depends on the locale (at least for the decimal point character [2], possibly for other things), so I doubt that the Spirit implementations would be correct (at least, not if used naively). I think lexical_cast would also not be correct, since it has a different locale-dependence from sprintf. [1] N3290 [string.conversions] p7 [2] N1570 7.1.1 p2 John Bytheway
