Getting WA on test 25, any test case?

2 2 2
2.01 4.01
3.99 4.01

правильный ответ 1.9800000
у меня было 1.9900000

Дело в том что чтобы не париться с double я умножал сразу на 100 но оказалось что 2.01 * 100 == 200 а не 201. Пришлось вручную переводить две цифры после запятой и решение зашло!

namespace _1489

    class Point
    {
        public double x;

        public double z;
        static void Main(string[] args)
        {
            int A, B, C;
            string S = Console.ReadLine();
            string[] SS = S.Split();
            A = Convert.ToInt32(SS[0]);
            B = Convert.ToInt32(SS[1]);
            C = Convert.ToInt32(SS[2]);

            double x1, y1, x2, y2;
            double[] mas = Console.ReadLine().Split(' ').Select(double.Parse).ToArray();
            x1 = Convert.ToDouble(mas[0]);
            y1 = Convert.ToDouble(mas[1]);
            double[] mas2 = Console.ReadLine().Split(' ').Select(double.Parse).ToArray();
            x2 = Convert.ToDouble(mas2[0]);
            y2 = Convert.ToDouble(mas2[1]);

            Point a = new Point();

                // A - x B - y C - z
                // x
                if (x1 <= C) a.x = 0;
                else if (x1 <= C + A) a.x = x1 - C;
                else a.x = A;

                // y

                if (y1 <= B) a.y = B - y1;
                else if (y1 <= B + C) a.y = 0;
                else if (y1 <= 2 * B + C) a.y = y1 - B - C;
                else a.y = B;

                // z
                if (y1 <= B) a.z = 0;
                else if (y1 <= B + C && x1 <= C + A && x1 >= C) a.z = y1 - B;
                else if (x1 <= C && y1 <= 2 * B + C) a.z = x1;
                else if (x1 >= C + A && y1 <= 2 * B + C) a.z = A + C + C - x1;
                else if (y1 >= B + C + B) a.z = 2 * (B + C) - y1;
                else a.z = C;

            Point b = new Point();

                // x
                if (x2 <= C) b.x = 0;
                else if (x2 <= C + A) b.x = x2 - C;
                else b.x = A;

                // y
                if (y2 <= B) b.y = B - y2;
                else if (y2 <= B + C) b.y = 0;
                else if (y2 <= 2 * B + C) b.y = y2 - B - C;
                else b.y = B;

                // z
                if (y2 <= B) b.z = 0;
                else if (y2 <= B + C && x2 <= C + A && x2 >= C) b.z = y2 - B;
                else if (x2 <= C && y2 <= 2 * B + C) b.z = x2;
                else if (x2 >= C + A && y2 <= 2 * B + C) b.z = A + C + C - x2;
                else if (y2 >= B + C + B) b.z = 2 * (B + C) - y2;
                else b.x = C;

            double difx = (a.x - b.x);
            double dify = (a.y - b.y);
            double difz = (a.z - b.z);
            //if (difx * difx + dify * dify + difz * difz > 0)
                Console.WriteLine((Math.Sqrt(difx * difx + dify * dify + difz * difz)));
            //else Console.Write(0);
        }
    }
}

I have wa8 when I used float numbers, when I changed it to double I get ac.

Please somebody help me, and give some tests, please!

My question is not particularly about this problem,
but about printf output with precision 10^-6 or better.

In this problem when I use float and output with printf("%.6f", ... ) I get WA8.
When I use double and printf("%.6lf", ... ) I get WA1.
What is the correct approach please?

Can you tell me why I am wrong in test 2 if you was wrong in test2 once?

How to control the output precision?What does "to the acuracy of 10-6?

I have had WA#3, but when I have tried following test, I pass Test#3, but have WA#13:

4 3 2
2.0 0.0
2.0 10.0

Right answer:
0.0000000

Now I have AC.

Please, someboby help me and give me some tests!

Can somebody say me, what is in test 10? I don't know, why i got WA...

Maybe there is a special case that is not mentioned in the problem or I didn't understand... Can you give some tests?

Thanks I got AC...
