Summary of the mailing list discussion (5 people participating)

  • Avoid the terms underflows/overflows as the thing we want to actually represent is lack of representability
  • Better justify the choice of values that defy industry practices and seem dangerous when error aren't check
  • Better motivate the paper as a whole (of the few participants in this discussion, no one seem to be arguing we need that)

LEWG will look at a revised paper (either meeting or telecon)
