the statement in the previous note is correct.  however, within the internal
logical of the processor, an extra bit of precision, namely the carry bit
is used to handle the most negative number.

one not remember not to confuse implementation from the algorithm.       
the algorithm works, but requires a n+1 bit implementation.
