   OK, I missed that part.   
      
   I had a need though in this case to specify an exact width for the   
   constant in some use cases, rather than merely just specify its largeness.   
      
   But, yeah, I and U / UI are non-standard, but alas...   
      
   Follows a similar pattern as for printf modifiers, say:   
      printf("%I64u\n", longValue);  //MSVC specific   
   Vs, say:   
      printf("%llu\n", longValue);  //Most everything else   
      
   In this case, the I notation being extended to also cover __int128   
   and _BitInt.
