rbinom (in R-1.4.1) silently rounds its "size" argument. 
  The C code contains 

    n = floor(nin + 0.5); 

  I would argue that this should this either be documented or changed (to 
return NA). (The behavior is inconsistent with dbinom). 

  I sent this in to the devel list a couple of weeks ago to
provoke discussion; no disagreement (or agreement) so I'm
submitting it as a bug.
