R help - Sep 2012 - max & summary contradict each other

why does summary report max 27600 and not 27603?
> x <- c(27603, 1)
> max(x)
[1] 27603
> summary(x)
   Min. 1st Qu.  Median    Mean 3rd Qu.    Max. 
      1    6902   13800   13800   20700   27600

Because you asked for 3 digit accuracy.  See ?summary.

Hi,
Try this:
summary(x,digits=max(5))
#?? Min. 1st Qu.? Median??? Mean 3rd Qu.??? Max. 
? #? 1.0? 6901.5 13802.0 13802.0 20702.0 27603.0 
A.K.
