Fx Calculator

This is a fairly typical full-screen calculator + it has an advanced editor screen where the user can type in more complex equations. The equation can use constants and functions listed below the edit field. The user can define their own constants and functions - they will be saved in a file and available for later.

The app is written using an experimental tech stack: Scala 3.3 + JavaFX 20 + GraalVM 22.1.0. It's open source. You can read more about it here:
