> Assuming that the locale issue isn't a problem, can that be reused? The to_chars patch uses C++14 features, while to_string is C++11. If that was solved, it probably could be used. However, as far as I know, simply using to_chars in to_string would technically be suboptimal, because it needs

libstdc++ has a to_chars implementation already. Assuming that the locale issue isn't a problem, can that be reused?

[PATCH] Add header implementation of std::to_string for integers (PR libstdc++/71108)

Currently std::to_string takes a fairly long trip to vs(n/w)printf. The patch implements int-to-string formatting in header, to improve function performance. Results of a benchmark on my PC: to_string(integer) takes 85-107ns per call (depending on result string size), out of which ~75ns is spent
