やばい論文を見つけた。たとえるなら，世界中でありふれた野菜炒めで世界一だと認められたようなもの。一刻も早く全文を読みたい。

Abstract

We present Ryu, a new routine to convert binary floating point numbers to their decimal representations using only fixed-size integer operations, and prove its correctness. Ryu is simpler and approximately three times faster than the previously fastest implementation.
