``` ![](example.png)
f(x, y) = sum(1, 3, (2sin4/x!)^y) + cos(n deg)
a = 3 ## Features
f(a, 2) * Operators: +, -, \*, /, !
``` * Groups: (), ⌈⌉, ⌋⌊
`>> 1.1899401098014355` * [Pre-defined functions and constants](https://github.com/PaddiM8/kalk/blob/master/kalk/src/prelude.rs)
* User-defined functions and variables. `f(x, y) = xy`, `x = 5`
* Understands fairly ambiguous syntax. Eg. `2sin50 + 2xy`
* Syntax highlighting
* Special-symbol completion on tab. Eg. write `sqrt` and press tab. It will be turned into `√`.
