calculate power of a number in .NET

The program calculates the power of a number using while loop and Math.Pow method in C#.NET.

Program:

namespace DotNetMirror
{
    class PowerOfNumber
    {
        static void Main()
        {
            double number, power, i = 1,sum = 1;
            Console.Write("Enter a Number : ");
            number = Convert.ToInt32(Console.ReadLine());
            Console.Write("Enter Power : ");
            power = Convert.ToInt32(Console.ReadLine());
            while (i <= power)
            {
                sum = sum * number;
                i++;
            }
            Console.WriteLine("{0} to the power {1} is: {2}", number, power, sum);
            Console.ReadLine();
        }
    }
}

Using Math.Pow Method:

Math.Pow is inbuilt method from System.Math Namespace. Math.Pow method returns a specified number raised to the specified power.

namespace DotNetMirror
{
    class PowerOfNumber
    {
        static void Main()
        {
            double number, power, sum = 1;
            Console.Write("Enter a Number : ");
            number = Convert.ToInt32(Console.ReadLine());
            Console.Write("Enter Power : ");
            power = Convert.ToInt32(Console.ReadLine());
            sum = Math.Pow(number, power);
            Console.WriteLine("{0} to the power {1} is: {2}", number, power, sum);
            Console.ReadLine();
        }
    }
}

Output:

Enter a Number : 3

Enter Power : 4

3 to the power 4 is: 81

Note: We are using Double datatype for sum,number and power variables. Please check for data range and change the datatype accordingly.
