A high-precision partially-symbolic calculator with support for units, derivatives, and more.

This is nowhere near complete. Stay tuned.


# TODO

## Before For 1.0 release
 - `+` as a unary operator
 - Compare operators => *, / should have the same priority!
 - Commands
 - Documentation (usage)
 - Documentation (comments)
 - Units


## General
 - CLI Options: version, help, evaluate
 - Compile to WASM => webapp
