Question

In this program I am trying to create a simple calculator. However, I can’t seem to find a way to overcome the aforementioned error when reaching the Math.Pow line.

namespace BinaryCalc
{
    class Binary
    {
        public static void Main()
        {

        int addition,subtraction;
        float division, multiplication, power, sqrt;

        int x;
        int y;
        x = 10;
        y = 7;

        //Console.WriteLine("Please enter a number for x");
        //string line = Console.ReadLine();
        //int x = int.Parse(line);

        //Console.WriteLine("Please enter a number for y");
        //string line2 = Console.ReadLine();
        //int y = int.Parse(line2);


        addition = (int)x + (int)y;
        subtraction = (int)x - (int)y;
        division = (float)x / (float)y;
        multiplication = (float)x * (float)y;

        power = Math.Pow(x,2);
        sqrt = Math.Sqrt(x);


        Console.WriteLine(" Addition results in {0}", addition);
        Console.WriteLine(" Subtraction results in {0}", subtraction);
        Console.WriteLine(" Division results in {0}", division);
        Console.WriteLine(" Multiplication results in {0}", multiplication);
        Console.WriteLine(" {0} squared results in {0}",x, power);
        Console.WriteLine(" Square root of {0} is: {0}", x, sqrt);

        }
    }
}

Answer 1

Math.Pow uses a double argument. As the error says, there is no implicit conversion from double to float, so convert the result explicitly to float:

power = (float)Math.Pow(x, 2);

EDIT
corrected the conversion order
