// Package GoMathExecutor provides simple expression executor.
|
|
//
|
|
// 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
