[Original GH Issue](https://github.com/rwaldron/proposal-math-extensions/issues/32)

The purpose of this method is to make it easy for devs to automatically convert any numeric value (`Number`s, `BigInt`s, maybe even `Decimal`s) to a string representing a binary data size/length/count, and being able to choose any standard system like SI or IEC (and maybe more in the future).

[This S.O. question](https://stackoverflow.com/questions/10420352/converting-file-size-in-bytes-to-human-readable-string) (and its comments) show how hard it is to get the implementation right, and the number of views and upvotes shows how useful such a function would be (yes, I'm aware I may have committed a fallacy).

JS code is often used to deal with files (or just data in general), and many times it is necessary to display statistics about the data in a user-friendly manner
