    do {
        let expression = try Expression(string: "10.2 - 10.1")
        let result = try Evaluator.default.evaluate(expression)
        print("result = \(result)")
    } catch {}
   //result = 0.0999999999999996

    do {
        let result = try "10.2 - 10.1".evaluate()
        print("result = \(result)")
    } catch { }
   //result = 0.0999999999999996
