   ////     the smallest b exponent (expo min) after prenorm is -52.
   ////     there is the possibility that a divide could create an artificially small Bexpo.
   ////     if that is true the shift right amount should be zero (right 64 followed by left 0).
   //// (2) otherwise the right shift amount comes from the product exponent.
   ////     the product exponent could be very small, however for a multiply add if it becomes
   ////     too small then the exponent will come from the addend, so no problem.
   ////     a multiply instruction does not have an addend, and it could have a very small exponent.
