For what it's worth, I think the utility of this is pretty niche and would be okay having to write it downstream.

Sure, why not

[JakeWharton]

I actually don't think this function should be in the library anymore. The need to perform such an operation makes very little sense in the context of a byte size. I only do it for sorting by the largest delta.

[Goooler]

I added the absoluteValue here, as this library supports negative values. This behavior differs from that of byteunits.

From my understanding, there should be an easy way to derive the absolute value from a negative value.

[JakeWharton]

Yeah I get that, but it's a weird operation to perform on a byte size in general. I don't really mind it being there, of course, since I will use it, but I also think it's perfectly reasonable to force something like this on user code.

Released as part of https://github.com/saket/byte-size/releases/tag/2.2.0. Thanks again!
