I'd never heard of him. He's done a lot of interesting stuff, mostly in high performance computing. From his personal page:

"Gustafson has recently finished writing a book, The End of Error: Unum Computing, that presents a new approach to computer arithmetic: the unum. The universal number, or unum format, encompasses all IEEE floating-point formats as well as fixed-point and exact integer arithmetic. This approach obtains more accurate answers than floating-point arithmetic yet uses fewer bits in many cases, saving memory, bandwidth, energy, and power."

Has anybody read it?

Are they planning to implement "The End of Error" (https://www.amazon.com/End-Error-Computing-Chapman-Computati...) algorithms?
