naturalsize() contains a very common but serious programming bug about humanize HOT 4 CLOSED

In which case are you finding a issue in the library?

Your post opens with the rounding problem but it seems to work fine in the lib:

>>> humanize.naturalsize(1023.59)
'1.0 kB'

Thanks!

If we're looking at binary sized (where the base is 1024) we never get anything like '1024.0 Bytes'.

The value is truncated, rather then being rounded, so you get something slightly surprising at the limit:

>>> import humanize
>>> humanize.naturalsize(1023.9999999999999, binary=True)
'1023 Bytes'
>>> humanize.naturalsize(1023.99999999999999, binary=True)
'1.0 KiB'

That looks like a different problem from the one that StackOverflow post describes though (if it's a problem at all – I'm not sure if it is).

Thanks @samueljsb! I just confirmed this weird behaviour in v3.13.1.
