thanx a lot for replying as i was really confused in this aspect

pls help me out whether Math.round(6.2) and Math.floor(6.2) will return same values. as acc to me the first one will return 6 while second wil return 6.0 that is first returns long value and second returns double value. Acc. to airthmetic 6 and 6.0 are same but i think acc. to java they r different what all of u say?
