Calculations, unit conversions and more inline in Text

Is your feature request related to a problem? Please describe.
When you create documents including units or financial data, you often immediately need to go for a spreadsheet. Spreadsheets are very hefty and seem very rigid and difficult to approach for people not working day to day with them.

For small calculations or unit conversions, a simple way to embed them in Text via writing them or even using natural language would be helpful.

Describe the solution you'd like
There is a popular MacOS app called Soulver which does this very well: https://soulver.app/
We don’t necessarily have to have a vertical split line, results could also be shown using a bubble next to the calculation in question.

Two further apps which do it similarly are https://www.figr.app/ and https://notepadcalculator.com/

There are also some JS libraries of differing quality:

• https://github.com/bbodi/notecalc3 → guide at https://bbodi.github.io/notecalc3/guide.html
• https://github.com/LorenzoCorbella74/soulver-web

Describe alternatives you've considered

• Not doing it cause it’s quite complicated to get right.
• Using AI to do the same?

@juliusknorr curious about your take and if you thought about it before.

Start by reviewing the Text editor and the referenced JavaScript libraries, including notecalc3 and soulver-web, to understand possible approaches to inline calculations and unit conversions. The issue does not identify files, tests, syntax, or a defined completion scope; done would require an agreed design and implementation for the supported calculations and their presentation.
