Description NISZ LibreOffice Team 2019-07-12 10:48:47 UTC
Description:
In Word it is possible to set preset widths for line objects: 0.25, 0.5, 0.75, 1.0 etc.  points.
After a roundtrip in Writer these are off by 0.01 points, which causes Word to not recognize them as the preset values.


Steps to Reproduce:
1.	Insert a shape in Word
2.	Go to Drawing tools -> Shape styles -> Outline and set some predefined width
3.	Save the file, open in Writer, resave.
4.	In the Word shape properties side bar under Shape Format -> Line -> Width you can see the value is off by 0.01 points: 1/4 -> 0.26, 1/2 -> 0.5, 3/4 -> 0.74,  1 -> 0.99, 1.5 -> 1.5, 2.25 -> 2.24, 3 -> 3.01, 4.5 -> 4.51, 6 -> 6.01


Actual Results:
Most values are off 0.01 points

Expected Results:
No rounding errors.


Reproducible: Always


User Profile Reset: No
