   This is supposedly a feature, not a bug.  I reported it many years ago, in a   
   published  review   
   of Mathematica, circa 1992.   
   The value x has many interesting properties including  x==x+1, also   
   x==1&&x==2  is True.   
      
   It is possible to counteract this phenomenon by explicit calls to SetPrecision,   
   but how are you supposed to know that. No other system that I am   
   aware of requires such a thing.
