   Since both formats have exactly identical semantics, in theory the mess   
   is not worse (and not better) than two bytes orders of IEEE binary FP.   
      
   I see much bigger problem [than BID vs DPD] in the fact that IEEE   
   standard does not specify few very important things about global states   
   and interoperability of BFP and DFP in the same process. Like whether   
   BFP and DFP have common rounding mode or each one has mode of its own.   
   The same question about for exception flags and exception masks.
