Hi,

I have a question about double addition in java 6. I tired following

double d1= 2.748 + 9.160;
System.out.println ( d1 );

I got following output 11.908000000000001 instead of 11.908 exactly.

Can anyone explain why it is so?


regards,
alim

To get the exact output use BigDecimal.

probably this will help you to understand why the output is like that.
