I just saw this on hacker news:We present Ryū, a new routine to convert binary floating point numbers to their decimal representations using only fixed-size integer operations, and prove its correctness. Ryū is simpler and approximately three times faster than the previously fastest implementation.Links: https://pldi18.sigplan.org/event/pldi-2018-papers-ry-fast-float-to-string-conversion https://www.youtube.com/watch?v=kw-U6smcLzk https://github.com/ulfjack/ryu

After a fast look at the texts, I can't find information about the optimality. They compare ryu mostly to grisu and grisu produces always correct, but not always optimal results, so it fallbacks to a slower algorithm for some values. It would be also nice to have some paper; I see only videos. Maybe a paper will come soon.We present Ryū, a new routine to convert binary floating point numbers to their decimal representations using only fixed-size integer operations, and prove its correctness.
