Heavy http://zim-wiki.org user here, but I do recall trying this out at some point and I can see a few use cases. Before I go digging, I seem to be seeing different opinions on how good of a "spreadsheet" type tool it is.
Specifically (right now), I'm curious as to what kind of math it's capable of? Right now I'm playing around with some cryptocurrency and I'm looking to play around with some custom views of prices and such, and I'm not quite sure how I want it to look; does this seem like a possible place to check it out?
The tutorial has a live example, and also lists the implemented operators.
If you want to do complicated formulas, you're almost certainly better off with a traditional spreadsheet. Or create a PR to extend it with operations you need :)
