            Bug ID: 143932
           Summary: horizontal pitch resolution limit disrupts label
                    spacing in Labels creator, formatting
           Product: LibreOffice
           Version: 7.0.6.2 release
          Hardware: x86-64 (AMD64)
                OS: Windows (All)
            Status: UNCONFIRMED
          Severity: normal
          Priority: medium
         Component: Writer
          Assignee: libreoffice-bugs at lists.freedesktop.org

Description:
I am trying to create a label type for a full sheet of 3/4 inch by 1/2 inch
labels of 9 columns and 16 rows. They are on standard letter-sized (8.5 by 11
inch) sheets. The margins and pitches are in 1/8ths and 1/16ths of an inch.
When I put in the correct horizontal pitch, vertical pitch, and margins, the
number is rounded to two decimal digits. The rounding error, when multiplied by
the number of labels, destroys the alignment to the actual labels when printed. 
I have tried inputting the measurments in the following ways:
0.625" which is converted to 0.63"
15.88mm which is converted to 0.63"
5/8 which is converted to 0.63"
The problem is that this is not just a "display" rounding, where the actual
measurement is correct internally. The internal number also seems to be rounded
to two decimal digits in inch units. I was hoping that it would also use two
decimal digits in millimeters, but no luck. 
This issue makes the label creation unworkable. I have 1/2 by 1/2 and 3/4 by
1/2 labels that require pitches and margins with greater resolution to make
them work. 
I can find no work around.
I see that there are other bug reports related to the two decimal digit issue,
but not for labels in writer. So, I am adding this to the list since it makes
printing to small labels useless. To further justify the need, these are small
asset tags that will have sequential numbers and company logo printed. There is
a need for the labels to work properly and be used with a database merge. 

Steps to Reproduce:
1. File/New/Labels -> format tab
2. Horizontal Pitch 7/8"
3. Vertical Pitch 5/8"
4. Width 3/4"
5. Height 1/2"
6. Columns 9
7. Rows 16
8. print out set of labels and see that the vertical and horizontal pitches do
not match the numbers entered and cannot print properly on label sheet. 

Actual Results:
Labels do not print at correct (entered) pitches. Rounding error causes
accumulated error in label placement and printing not within label bounds.

Expected Results:
Printing would be properly positioned on the labels in the positions as entered
into the label creation form. 


Reproducible: Always
