This is a port of ChatCalc by RTTV (which is also a port of ChatCalc by Kokeria) to the newest minecraft versions, because it hasn't been updated in a long time. It's also completely converted from Java to Kotlin, just because I can.
The functionality hasn't changed much, so you can check the original mod's description. There is, however, an additional dependency - Fabric Language Kotlin - which is needed for Kotlin to work.
I do plan on adding some features later, such as better config handling and allowing calculations in text fields other than chat, like signs (done), books, anvils etc. They aren't available yet, though. If there's anything else that you want to see in the mod, please create an issue on github.
