   Can someone tell me if the following query:   
      
   select bitand(power(2,31),power(2,30))+0   
   from dual   
      
      
   which returns 1073741824 is correct ? I'm thinking that the result   
   should actually be 0.   
      
      
      
   When I run   
      
   select bitand(power(2,30),power(2,29))+0   
   from dual   
      
      
      
   I get 0, as expected.  Am I running into a limitation of the bitand   
   function ?  Is there any documentation on this function?   
      
      
   Thanks.
