Just saw this on Hacker News: https://pldi18.sigplan.org/event/pldi-2018-papers-ry-fast-float-to-string-conversion

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.

I haven't investigated in the slightest, but it sounds like something that would be valuable to implement in the Ion serializers.

Looks promising. I've added a related issue to ion-c.
