Frink (https://frinklang.org/) is an older language with similar design goals.

Frink runs on the JVM and is also available on Android.

I use it as a general purpose calculator on my smartphone.

It's really nice that Numbat is written in Rust :) Will have to try it out.

There's also Insect for interactive use: https://insect.sh/

Insect is the predecessor project. Numbat is the replacement. It also has an interactive version at https://numbat.dev/

Frink is not open source, unfortunately.

Thanks for sharing Numbat with us.

It looks great!
