–Issue reported first at bugzilla.red hat 1582165
<https://bugzilla.redhat.com/show_bug.cgi?id=1582165>–

OS :Fedora
Version-Release number of component: coreutils.x86_64 8.29-6.fc28 @updates

1. Accuracy

Actual results: In terminal, outputs resulting from the execution of
command:
– 'df -h' are specified at best with one digit accuracy.

Enhancement: An accuracy with two digits (model 0.00 M) would be
appropriate.

2. Documentation

Actual results: Df tool displays sizes associated to data storage observing
the notation (k, M, G, ...) while obviously outputs resulting from 'df'
tends to indicate that actually, by default sizes associated to data
storage are specified by observing the international standard ISO 80000
–also known as IEC 80000– which sets the convention regarding binary
prefixes (e.g. 1024 = 1 Ki = '1 kibi') in that field. But that is all a
deduction.

'man df' lacks valuable information related to that policy that required to
be established in man page.

Enhancement: above mentioned policy to be dully documented.

3. Conventions

Actual results: Convention used regarding the signs '%' and Metric prefixes
(k, M, G, ...)  attached along with data storage values –made upon format
(model 0%)– is the one that applies to American English and British English
and others countries attached to the British crown. Nevertheless others
countries' convention regarding values an units representation observe a
format which introduces a space between values and units (here as model: 0
%).

Furthermore readability of expressions displayed in such formats are not
equal; model '0 %' is superior to '0%'.

Enhancement: As expected model '0 %' is the one who fill higher purpose.

4. Basic units of measure are missing (by policy, not as result of an issue)

Actual results: Basic units of measure are missing since only metric
prefixes are displayed.

Enhancement: Since unit prefixes illustrated here are in this context
likely to indicate nothing else but multiples of the unit proper to digital
information, characters 'b' or 'B' and their equivalents for others
supported system languages must be considered to be part of the designation.

Additional info: Metric prefix is a unit prefix that precedes a basic unit
of measure to indicate in that case a multiple of the unit.
