c# - there is a strange behaviour double parse string input?

i try to read some excel file and converting some string column to save in db. BUT i face to face some double parse error: double result = double.Parse( 1,15); result: 1.149999999999.... i dont want to see this. i want double result = double.Parse( 1,15); result = 1.15


 static void Main(string[] args)
        {
            NumberStyles styles;
            IFormatProvider provider;

            styles = NumberStyles.Float;
            provider = CultureInfo.CreateSpecificCulture("tr-TR");

            string test = "1,15";
            double result = double.Parse(test, styles, CultureInfo.CreateSpecificCulture("tr-TR"));
            Console.WriteLine(result.ToString());
        }
    }

Use the decimal data type for DB and Application if you need the high precision data types.
