Interestingly, JRuby always has been using scientific notation for this. |
e.g. ``` JSON.dump(1746861937.7842371) ``` master: ``` "1.7468619377842371e+9" ``` This branch and older json versions: ``` 1746861937.7842371 ``` In the end it's shorter, and according to `canada.json` benchmark performance is the same.

For reference, sidekiq was using a bad regexp to parse JSON and was broken by this change: sidekiq/sidekiq#6700. I'm not considering using scientific notation to workaround that bug, but I think it's better overall.
