Via sizes won't stay exact

[TomCC]

Hi!

Following issue:

1. Set DRC rules and "default" netclass in pcbnew as min track width 0,2 mm, min. via size 0,6 mm, min. drill size 0,3 mm.
2. Use Push and shove routing.
3. Start creating a track, using W to change track width to the specified minimums.
4. Again press W and note that instead of 0,6 and 0,3 the sizes are shown as 0,59999(or 8) and 0,299999.
5. Create a via and end the track.
6. Use DRC

DRC reports the created via as undersized.

Currently I'm bypassing this bug with Search and replace .kicad_pcb file editing.

If this is already fixed in newer versions, I apologise, I couldn't find a bug reporting it.

Problem caused by using double<>int conversion, sometimes loosing accuracy. Will fix in the upcoming P&S release.

[Maciej Suminski (orsonmmz)]

It has been fixed (switched to integer instead of double) when the Differential Pair router was merged (revision 5468).

Thank you! just confirmed that the bug no longer occurs (happened to have a build from the next day after 5468 installed)
