Description rayhogenson 2014-08-26 09:24:09 UTC
Problem description:
When typing in a manual font size, such as 10.7, the font rounds off to a multiple of 0.2 or a multiple of 0.5.  I can't see a reason why all sizes can't be supported.

Steps to reproduce:
1. Open a document
2. Click in the font size box, and type in 10.7
3. Font size is changed to 10.6

Current behavior:
Font sizes are rounded to a multiple of 0.2 or 0.5.

Expected behavior:
Any font size should be acceptable, and possible to use.
              
Operating System: Linux (Other)
Version: 4.2.6.2 release

Hello rayhogenson,

Thank you for submitting the bug. I can confirm this behaviour in 3.3.0 and master, though i'm not sure if this is something worth fixing as values rounded to the closest .1 are not that different that ones rounded to .2, but i will await others to opinion on this.

Under GNU/Linux using v4.3.1.2 I see different behaviour. This is what I see displayed after manually editing the Font Size value in the toolbar:

Entered Displayed fo:font-size
------- --------- ------------
12.0    12        12pt
12.1    12.1      12.1000003814697pt
12.2    12.1      12.1999998092651pt
12.3    12.3      12.3000001907349pt
12.4    12.3      12.3999996185303pt
12.5    12.5      12.5pt
12.6    12.6      12.6000003814697pt
12.7    12.6      12.6999998092651pt
12.8    12.8      12.8000001907349pt
12.9    12.8      12.8999996185303pt
13.0    13        13pt

The text, as rendered on screen, does actually change size in each and every case, it is just the display in the toolbar / sidebar that appears to be rounded off (rather than up). This may be a floating point issue.

If the font size in use is changing, but the displayed size is not, then that's definitely a bug we should address, regardless of whether we decide to round font sizes to a particular tolerance.

Removing need*Advice tags from the whiteboard.

Thanks Robinson. Summary amended for clarity.

This bug has been annoying me for years.  Note that it only displays incorrectly on the toolbar.  If you check your font under format-> character it will show the correct value.  It is pretty amazing how long this bug has been affecting OO/LO.

In comment #2, I have no idea where he is getting those "fo:font-size" values.

Thanks for pointing out this other place.

These are the values stored in the odt xml file (attachment 106240 [details]).
