Last but not least... when the tools print values like "10.00 GiB 10.74
GB"... wouldn't it be better if they printed "~10.00 GiB ~10.74 GB" or
something like this to show that the values are rounded and not
_exactly_ 10 GiB... could be helpful to avoid misalignment issues.

Would that really help?  Given that 10.00GiB is not exactly the same as
10.74GB, isn't it obvious that they must be approximations?

I'm not exactly against adding '~' but it doesn't seem necessary.
Does anyone else have thoughts?

When I studied rounding I was taught that 10.74 implied values could be 
between 10.744999999... and 10.735000000... Same goes with 10.00 can be 
between 10.004999999... and 99.995000000...

As long as the value numbers are correctly rounded, I don't feel there is 
a need to put the "~" in there. 10.74GB doesn't imply 10.7400000000000.
