Comment 14 for bug 410310

The missing float conversion had the effect of cutting off the decimal fraction of the size and has meanwhile been fixed.

There, however is a second part to this bug:
When doing an update with update-manager some numbers displayed on screen come from update-manager and some from apt.
And now apt is displaying the numbers with decimal kilos (K=1000), and update-manager is displaying the numbers with binary kilos (K=1024). Even if the float problem is solved, this still gives a difference in display of about 4.8% for Megabyte numbers. (see some more details in my comment #9 above and some of the attached pictures).

Before this bug is set to 'Fix Released' I would like to raise the question if it would make sense to consistently use one and the same factor for kilo/mega representation throughout all package management programs. This could be done either by changing humanize_size to decimal as well, or changing apt/apt-pkg/strutl.cc to binary, or even by totally eliminating humanize_size and using also the apt subroutines in update-manager.

As far as I can see there is even another weakness in humanize_size (at least in older versions, I have not checked the most recent ones yet): the localization of the decimal separator is not correct and always displayed as '.' even in 'decimal point is comma' local settings as with German language.
