Wrong. You once again fell for displayed precision != stored precision:

Here is the example I use days ago:

   R> print( as.numeric( Sys.time() ), digits=20 )
   [1] 1307296635.9376249313

whereas when I do it now without the digits= override:

   R> print( as.numeric( Sys.time() ) )
   [1] 1307477616


   R> typeof( as.numeric( Sys.time() ) )
   [1] "double"


Gauss once played himself in a zero-sum game and won $50.
