Very cool, though I find there's a lack of discoverability as to what I can do with it, and no help is provided if there's an error.

    pi() => 3.14...
    sin(3.14 rad) => 0.00..
    sin(pi() rad) => err

No idea why there's that error.

Thanks for noticing it!

Unfortunately it seems units cannot be applied to function results. It must be fixed, I noted down, thanks!
