instead of cutting it off by using int
especially relevant currently with 2 TB disks (people wonder why
it's displayed as 1 TiB - and would be fine with 1.95TiB).
Reported in our community forum:
https://forum.proxmox.com/threads/.103636/
Tested in a VM with a 100 GiB, 20GiB and 2TiB disk
Addtionally added the explicit return ath the end of the if branch,
instead of relying on the last statement not moving.

Alternatively we could also use sprintf without decimal places for rounding
(Math::Round is a debian package of it's own) - if people consider
20.00GiB to not look too pleasing
Thanks to Dominik for insisting to see the code on this and suggesting
to actually improve it :)
