   I remember one of Kahan’s writings suggesting it is useful for testing   
   numeric stability: if your code gives results that differ only slightly in   
   the four different rounding modes, then your calculations are *probably*   
   stable; if the results vary a lot, then your calculations are *probably*   
   unstable.
