Kalk is a calculator (both program and library) that supports user-defined variables and functions.
|
|
|
|
|
|
|
|
## Features
|
|
* Operators: +, -, \*, /, !
|
|
* Groups: (), ⌈⌉, ⌋⌊
|
|
* [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 `√`.
|
|
* Sum function: `sum(start, to, expression)` Eg. `sum(1, 3, 2n+1)` is the same as `2*1+1 + 2*2+1 + 2*3+1` = `15`
