Description
I'm proposing a replacement of missing/dtoa.c with a faster, leaner, more correct algorithm. I have a PR open as a proposed solution, which also provides more details to the origin of the algorithm and its performance compared to missing/dtoa.c.
This would solve a few edge case rounding issues that currently happen during Float#to_s, and it would significantly increase the performance of Float#to_s and String#to_f, all while unifying both formatting (shortest-width and fixed-width) and parsing under one primitive.
