WS=> Of course this is not an answer to your question, but what do you 
mean by "smallest integer"?  Mathematically, there is no such thing as 
"smallest integer" because integers are infinite.  In computer science, 
it depends on how much space is set aside to represent integers.  Is it 
a single byte, a word, etc.?
