Re: [math-fun] posits, IEEE floats, asinh numbers
Is there a write-up of posits that actually specifies how the regime bits work--I couldn't really tell from the Gustafson slides. Is there aparameter besides the total number of bits that needs to be specified?
It should be in this book: The End of Error: Unum Computing (Chapman & Hall/CRC Computational Science) – February 5, 2015 by John L. Gustafson (Author) <https://www.amazon.com/End-Error-Computing-Chapman-Computational/dp/1482239868/ref=sr_1_1?s=books&ie=UTF8&qid=1413144875&sr=1-1&keywords=end+of+error+gustafson>

Are you sure? Posits are not the exact same thing as unums. -- g

No I'm not sure. I haven't been following the discussion carefully. The book is apparently a "recent" ("revolutionary" <https://www.amazon.com/gp/product/1482239868?keywords=the%20end%20of%20error%20unum%20computing&qid=1456088488&ref_=sr_1_1&sr=8-1>) book by the author of the slides. http://johngustafson.net/ I figured mistakenly that it would cover the details of his talk. I just downloaded a copy of the book. A search for "posits" in the book finds nothing. The book carries the date 2015, but in the slides posits (simoid unums?) are given a date of 2017.
