[rrd-users] Re: RRDTool::OO - Storing/Retrieving from DB

[Rafael Angarita]

    Thanks for your answer Mike, but I have just one more question, is 
normal a rounding as big as this? (my program add the received 
parameter). I 50, 50 and 40 and the 40 is added as 42

# for i in 50.0 50.0 40.0 ; do
        perl graphQueue.pl.old $i;
        echo "";
        sleep 5;
    done
  Adding 50.0
 
  Adding 50.0
Fri Jul  9 09:27:50 2004: 50
Fri Jul  9 09:27:55 2004:
 
  Adding 40.0
Fri Jul  9 09:27:50 2004: 50
Fri Jul  9 09:27:55 2004: 42
