Calling from a public class and from its public method, into 2d double array, my zeros before the fractional point change to number 9. What is this? : So I've been writing a program, to use it as a tool for quick calculations in an online game, and it also helps me a bit to revise C# for my final exam in IT.

Here's my code:

    public class ConvertingToArrays
    {
       public static double[,] CountryVAT(double[,] vat)
        {
            vat = new double[20, 1];
            string[,] convertTableToString = new string[20, 6];
            convertTableToString = ReadFromFile.Input(convertTableToString);            
            for (int i = 0; i < 20; i++)
            {
                for (int j = 0; j < 1; j++)
                {
                    vat[i, j] = Convert.ToDouble(convertTableToString[i, 1]);
                    
                }
            }
            
            return vat;
        }
    }

With the string to double converting I had no problem, I tested it and it should not be the cause.

    class Program
    {
        public static void Main(string[] args)
        {
            double[,] vat = new double[20, 1];
            vat = ConvertingToArrays.CountryVAT(vat);
            Console.WriteLine("Testing Convert to vat Method Call");
            for (int i = 0; i < 20; i++)
            {
                for (int j = 0; j < 1; j++)
                {
                    Console.Write(vat[i, j] + '\t');
                }
                Console.WriteLine('\n');
                
            }
            Console.ReadKey();
        }
    }

I'm reading from a .txt file a few numbers: 0,03; 0,05; 0,4; 0

And for some reason the output for these numbers are: 9,03; 9,05; 9,4; 9

I've tried to look it up on google but I found nothing, and I'm a bit angry that I can't solve it. It might be just one subtle and easy thing that I overlooked accidentally (please keep in mind that I have started learning to code by myself just 6 months before and I've practiced it only 10-12 hours a week).

Can anyone help me out with a solution?
If you need any more information or code snippets, I put it up ASAP.
