Is there a way to configure Inkscape to use whole numbers in the interface rather than decimals for common properties?
You can try to configure Inkscape for saving no decimals whatsoever.
- File > Inkscape Preferences > SVG Output
- Numeric precision > set to 0
There appears to be no option currently available to do this. As prokoudine suggested, I have opened a feature request. It can be tracked here:
