We'll probably never have perfect representation of real numbers, but Gustafson's unums seem to be the next best thing that can actually make a difference. His examples of how unums can solve the trickiest numerical challenges are impressive. http://insidehpc.com/2015/03/slidecast-john-gustafson-explains-energy-efficient-unum-computing/ http://insidehpc.com/2015/03/slidecast-john-gustafson-explai... http://radiofreehpc.com/tmp/TheEndofErrorSampleChapter.pdf http://radiofreehpc.com/tmp/TheEndofErrorSampleChapter.pdf
