On my research list: Unum – The End of (Numeric) Error
Posted by jpluimers on 2020/06/24
From about 4 years ago, so time to see how many development stacks support Unum by now: [WayBack] The End of (Numeric) Error
Crunching numbers was the prime task of early computers. The common element of these early computers is they all used integer arithmetic. John Gustafson, one of the foremost experts in scientific computing, has proposed a new number format that provides more accurate answers than standard floats, yet saves space and energy. The new format might well revolutionize the way we do numerical calculations.
