				Hi
1) I am trying to divide two numbers in a TCL script but what I get
is the ceiling of their ratio e.g 73/125 -> 0.do you know where this comes
from?
2) I am simulating a link of queues.Although I am using random numbers for
the loss rates in each queue (the random number generator is properly
seeded each time) for the first queue ONLY I get a constant number of
dropped pkts i.e each time I send 1000 pkts and 825 are dropped.Do you
have any idea about this?
3) I have placed a queue monitor in each queue.In each queue if I add
pdepartures plus pdrops_ I dont' get always parrivals_, some pkts are
missing.Can you explain that?
			       Thanks
