    // old method
    temp changed by more than 10%
    if (Math.Abs(e.NewTemperature - e.OldTemperature) > 0.10)
    {
        Console.WriteLine("Temperature changed by more than 10%");
    }
    
    if (Math.Abs(e.NewHumidity - e.OldTemperature) > 0.10)
    {
        Console.WriteLine("Humidity changed by more than 10%");
    }

    // new method
    // lambda, static to not capture anything
    static bool isWithinPercentage(double value1, double value2, double decimalPercentage) => (Math.Abs(value1 - value2) <= decimalPercentage);
    if (!isWithinPercentage(e.NewTemperature, e.OldTemperature, 0.10))
    {
        Console.WriteLine("Temperature changed by more than 10%");
    }

    if (!isWithinPercentage(e.NewHumidity, e.OldHumidity, 0.10))
    {
        Console.WriteLine("Humidity changed by more than 10%");

    }
