[libcxx-commits] [PATCH] D59178: [libc++] Speedup to_string and to_wstring for integers using stack buffer and SSO

[Afanasyev Ivan via Phabricator via libcxx-commits]

ivafanas added a comment.

Vlad, yes, you are right, `std::to_chars` produce unexpected result for the specific range of values.

I will try to fix that and add tests.
It is needed to make sure that `std::from_chars` will be able to understand both `std::to_chars` outputs in order to save compatibility.
