# eval

A minimalistic math parser for Go. It implements the [shunting-yard-algorithm](https://brilliant.org/wiki/shunting-yard-algorithm/)

and allows to parse math from strings.

## Work in progress

The current implementation requires spaces between each math token and does not support trigionometric functions yet.

## Example

The library can be used as illustrated below:

```go

package main

import (

	"fmt"

	"github.com/jacalz/eval"

)

func main() {

	input := "( 6 - 2 * ( 6 / 3 ) ) ^ 3"

	

	result, err := eval.Evaluate(input)

	if err != nil {

		panic(err)

	}

	fmt.Println(result)

}

```

A more elaborate example can be found in the `example` folder.
