Hi all,
I got one intresting problem with caliculating mean that is

while i am taking mean of values

*0.6, -0.8, 4, -3.8*

using
*val<-c(0.6, -0.8, 4, -3.8)*
*mean(val)*
it given result as
*2.775558e-17*

but the actual result is  *"0"*

can any one suggest how can I get correct mean result in this case

can any one suggest how I can farward

thanks in regards

kiran
