Are there any 64-bit number proposals under consideration?

[Brandon Andrews]

You can view the current proposals here: https://github.com/tc39/ecma262


There are none that mention 64-bit types. The closest might be the "Typed Objects" proposal.


I started a competing type proposal (still in the theory stages) here https://github.com/sirisian/ecmascript-types in an effort to define types into the core language. (Compared to adding ad-hoc objects for every proposed type). Something like that would take years progress through the proposal system though. (Been too busy to finalize it and present it for stage 0).


Right now the lack of 64-bit integer types is also holding back the TypedArray stuff from supporting them. There was also this post from 4 years ago: https://esdiscuss.org/topic/value-objects

Not much progress on any fronts though from what I've seen. From reading a lot of the mailing list casually there were quite a few users against adding more types or extending the language with types in the past. Not sure if they're still here though.
