screenshot of Create a new partition dialog showing the default entries for a
new partition on a 1.87 GiB gpt tabled device.
SUMMARY
The New Partition dialog has three (3) numeric entry inputs. Each input shows
two decimal places, but only allows whole numbers. The sizes entered here are
thus limited to whole numbers of the Preferred Unit as selected in the Advanced
Settings. This restriction also seems to apply to defaulted/automatic values in
some cases.
STEPS TO REPRODUCE
1. with device with unallocated space, initiate the New partition dialog (click
new button or context menu item) Preferably the unallocated space is not a
whole number of the current Preferred Unit.
2. Observe the Size value will be automatically set to the rounded down whole
number of the available space rather than the near actual space to the
indicated two(2) decimal places. Note that the Visual display above shows the
intended size.
3. Creating the partition:
a. If the user does not try to alter the amounts and clicks "OK" then the
size of the partition is as the default should be. This indicates that the size
input has the proper value, but incorrectly does not display it.
b. If the user tries to alter the value of the size several different things
can happen:
- using the example of a 1.87GB drive the initial values show Free space
before: 0.00 GiB, Size: 1.00 GiB, Free space after: 0.00 GiB
-- Set focus to the Size input and type "1.2": the "1" replaces the existing
number, now showing "1 GiB" with cursor after the "1". the "." is added, now
showing "1. GiB" cursor after the ".", Typing the "2" results in no changes as
the 2 is not added. A zero is permitted to be added however.
-- (again from start) Using the decrement arrow once reduces the size shown
in the visual representation from 1.87 GiB to 1,023.00 MiB, the Size input is
unchanged until the size changes from 1019.00 MiB to 1018.00 GiB then shows
0.99 GiB and the Free space after input changes to show 0.87 GiB, the increment
arrow on the Size input is now enabled. Using the increment operation (either
with the button or the up key on a keyboard) the size can be increased until
1.00 GiB but no further.
-- Using the mouse pointer to move the visual representation's handles
(either size of the new partition) does allow the size to be changed as
expected. During the size change in this way, the Size and Free space inputs
show values as expected.
OBSERVED RESULT
Unable to change numeric inputs directly except by whole numbers, using
increment & decrement operations of an input allows finer grained changes, but
the increment is capped at the floor of the available size.
EXPECTED RESULT
The default value should show the actual value with the indicated two decimal
places.
Should be able to change the size to a valid value (between Min and Max size)
using the keyboard to type in a value with non-zero decimal values.
Should be able to use the increment operation of a numeric input to increase
to the actual maximum value rather than the floor (rounded down whole number)
of the maximum value.
