[castor-user] JDO: with float (where is the precision coming from?)

[Eric Anderson]

I have some java code like this

 public float getTimetaken(){
        
          float retVal = 0;
          long tempVal;
          
          
          tempVal =  (System.currentTimeMillis() -
last_checked_time.getTime());
          
          retVal = (float) tempVal / 1000;
          
         
last_checked_time.setTime(System.currentTimeMillis());  
          
          System.out.println(tempVal+"  " + retVal);  
                  
          return retVal ;
  }

mapping is like this

<field name="time_taken" type="float"><sql name="time_taken"
type="float"/></field>

tempVal is always a 4 digit number, and retVal is always 3 or less
decimal places (which it should be x / 1000)).

But when it updates the database it alwasy get float values many
decmial places (like 10) that have added values. Anyone know why?
