-    //   zero.  The Java programming language uses two's-complement

-    //   values is not symmetric, so negation of the maximum negative
-    //   int or long results in that same maximum negative number.
-    //   Overflow occurs in this case, but no exception is thrown.
-    //   For all integer values x, -x equals (~x)+1.''
