(9) (since C++11)

Converts a numeric value to std::wstring.

1) Converts a signed decimal integer to a wide string with the same content as what std::swprintf(buf, sz, L"%d", value) would produce for sufficiently large buf.
2) Converts a signed decimal integer to a wide string with the same content as what std::swprintf(buf, sz, L"%ld", value) would produce for sufficiently large buf..
3) Converts a signed decimal integer to a wide string with the same content as what std::swprintf(buf, sz, L"%lld", value) would produce for sufficiently large buf.
4) Converts an unsigned decimal integer to a wide string with the same content as what std::swprintf(buf, sz, L"%u", value) would produce for sufficiently large buf.
5) Converts an unsigned decimal integer to a wide string with the same content as what std::swprintf(buf, sz, L"%lu", value) would produce for sufficiently large buf.
6) Converts an unsigned decimal integer to a wide string with the same content as what std::swprintf(buf, sz, L"%llu", value) would produce for sufficiently large buf.
7,8) Converts a floating point value to a wide string with the same content as what std::swprintf(buf, sz, L"%f", value) would produce for sufficiently large buf.
9) Converts a floating point value to a wide string with the same content as what std::swprintf(buf, sz, L"%Lf", value) would produce for sufficiently large buf.
