Hi all, I’ve been working on this Rust project for a while now, and hope someone might find it useful. It’s written as a CLI app, and there’s also a WebAssembly version you can try out at at https://printfn.github.io/fend-website.

It has support for unit conversions, number base conversions, fractions, complex numbers, variables and D&D-style dice. There’s a bunch of examples in the GitHub README, as well as the manual at https://github.com/printfn/fend/wiki.

Please let me know what you think!
