Use the while statement to implement Newton's method for finding the square root : Double Calculation : Data Type C# Examples

    
using  System;

public  class  MainClass  {
      public  static  void  Main(  )  {
        double  epsilon      =  1.0e-9;
        double  guess        =  11.0;

        double  value  =  2;

            double  result  =  ((value  /  guess)  +  guess)  /  2;

            Console.WriteLine(  "Guess  Value    =  {0}",  guess    );
            Console.WriteLine(  "Result  Value  =  {0}",  result  );

            while(  Math.Abs(result  -  guess)  >  epsilon  )  {
                    guess  =  result;
                result  =  ((value  /  guess)  +  guess)  /  2;
                    Console.WriteLine(  "Guess  Value    =  {0}",  guess    );
                    Console.WriteLine(  "Result  Value  =  {0}",  result  );
        }

        Console.WriteLine("The  approx  sqrt  of  {0}  is  {1}",  value,  result  );
