Dear Sir/Madam

Sir

I am trying to write a program which check the format:

123.4567899 which is allowed.

The max no. of digit for integer part is 3 and the max of digit after the
decimal is 7 so total max length is 11.

It is very strange that when enter 0.45 in the result, it is positive.
But it is exception when enter 0.55 - 0.58

public static void main(String[] args) {

               Double result = null;
                               //can try from 0.55 - 0.58 wont work

               result = Double.valueOf((String)"0.55");
               double netResult = 0.00;
               double netResult1 = 0.00;
               int decimal = 7;
               netResult = result.doubleValue() * Math.pow(10,decimal+1);
               netResult1 = netResult % 1;
               if (netResult1 >0){
                       System.out.print("Exception");
               }
               else{
                       System.out.print("OK");
               }
               System.out.print("\nResult = "+result);
               System.out.print("\nResult.doubleValue =
"+result.doubleValue());
               System.out.print("\nnet Result = "+netResult);
               System.out.print("\nnet Result1 = "+netResult1);
}

It is all OK for value except from 0.55 to 0.58 which throw exception,
Any clue?

Please kindly help
