eval

A minimalistic math parser for Go. It implements the 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:

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.
