Hello,

I found that round() does not behave as I expected.
Have you had similar experience as following?

> x<-seq(0.5,10.5,by=1)
> x
[1] 0.5 1.5 2.5 3.5 4.5 5.5 6.5 7.5 8.5 9.5 10.5
> round(x)
[1] 0 2 2 4 4 6 6 8 8 10 10
> cbind(x,round(x))
     x  
[1,] 0.5 0
[2,] 1.5 2
[3,] 2.5 2
[4,] 3.5 4
[5,] 4.5 4
[6,] 5.5 6
[7,] 6.5 6
[8,] 7.5 8
[9,] 8.5 8
[10,] 9.5 10
[11,] 10.5 10


Is this a well-known bug?

Thanks in advance,
