Package GoMathExecutor provides simple expression executor.

## Installation

`go get github.com/neonxp/GoMathExecutor`

## Usage

```

calc := executor.NewCalc()

calc.AddOperators(executor.MathOperators) // Loads default MathOperators (see: defaults.go)

calc.Prepare("2+2*2") // Prepare expression

calc.Execute(nil) // == 6, nil

calc.Prepare("x * (y+z)") // Prepare another expression with variables

calc.Execute(map[string]float64{

	"x": 3,

	"y": 2,

	"z": 1,

}) // == 9, nil

```
