The arithmetic plugin uses `eval`

to evaluate the expression. It would be possible to ignore suffixes of numbers like that if you strip them with a regex replace before. In fact, you can apply the following changes using the *ViewPackageResource* package:

, but you’ll understand what to change if you need to.
