Number decimals problem

After interpolating and using an instance as a master some of the glyph widths are now showing impossible fractional values. Is there a way to round them off to a whole number? I need to apply this to the whole fonts as there are now many instances of this.

The width was like that in previous versions. I just changed it that is shows now.

?
OK. How do I do it?

You need to somehow trigger a change of the width. Or remove the fractional part. Or write a small script.

I added it that Path > Round Coordinates will do that, too.

Thanks. I just global shifted then reversed it and that worked.
