Re: values for fields in failure/exception

In my program I need to return a result object as below

class MyResult {
     private boolean success;
     private double distance;
     private String matchFileName;
     private String message;

     public MyResult (boolean s, double d, String mfn, String msg) {
         this.success = s;
         this.distance = d;
         this.matchFileName = mfn;
         this.message = msg;
     }
     //getters and setters...
}

In my program , I am returning a MyResult instance containing values
from a calculation.If an exception occurs ,I would like to return the
object with values which represent a failed calculation .The problem
is that,I cannot put distance as 0.0 since it is one of the valid
distance values.
So I put distance as Double.NaN.I don't know if this is the correct
way..Can someone suggest a better solution?

public MyResult getResult() {
     MyResult res = null;
     try{
         res = calculate();

     }catch(SomeException e) {
         return new MyResult ( false, Double.NaN, "", e.getMessage() );

     }
     return res;
}
