Decimal filesize YB to ZB rollover doesn't happen where expected #205

Description

@asmacdo

For all smaller units, we never see 1000, it always rolls over to the next.

What did you do?

In [5]: from humanize import filesize
In [6]: filesize.naturalsize(100_000_000_000_000_000_000_000)
Out[6]: '100.0 ZB'

In [7]: filesize.naturalsize(1_000_000_000_000_000_000_000_000)
Out[7]: '1000.0 ZB'

In [8]: filesize.naturalsize(10_000_000_000_000_000_000_000_000)
Out[8]: '10.0 YB'

The exact rollover happens here:

In [66]: filesize.naturalsize(1_000_000_000_000_000_050_331_648)
Out[66]: '1000.0 ZB'

In [67]: filesize.naturalsize(1_000_000_000_000_000_050_331_649)
Out[67]: '1.0 YB'

What did you expect to happen?

Id expect to see 1 YB rather than 1000 ZB.

What versions are you using?

  • OS: 6.10.9-200.fc40.x86_64 (Fedora 40)
  • Python: 3.11.5
  • Humanize: 4.10.0

I assume this is just a floating point precision limitation, so probably no fix is needed.
