The End of Error: Unum Computing (Paperback)

The Future of Numerical Computing

Written by one of the foremost experts in high-performance computing and the inventor of Gustafson’s Law, The End of Error: Unum Computing explains a new approach to computer arithmetic: the universal number (unum). The unum encompasses all IEEE floating-point formats as well as fixed-point and exact integer arithmetic. This new number type obtains more accurate answers than floating-point arithmetic yet uses fewer bits in many cases, saving memory, bandwidth, energy, and power.

A Complete Revamp of Computer Arithmetic from the Ground Up

Richly illustrated in color, this groundbreaking book represents a fundamental change in how to perform calculations automatically. It illustrates how this novel approach can solve problems that have vexed engineers and scientists for decades, including problems that have been historically limited to serial processing.

Suitable for Anyone Using Computers for Calculations

The book is accessible to anyone who uses computers for technical calculations, with much of the book only requiring high school math. The author makes the mathematics interesting through numerous analogies. He clearly defines jargon and uses color-coded boxes for mathematical formulas, computer code, important descriptions, and exercises.

《數值計算的未來》

這本書由高性能計算領域的專家之一、Gustafson定律的發明者所撰寫，《錯誤的終結：Unum計算》解釋了一種新的計算方法：通用數字（unum）。通用數字包括所有IEEE浮點數格式，以及定點數和精確整數運算。這種新的數字類型在許多情況下可以獲得比浮點數運算更準確的答案，同時使用更少的位元，節省記憶體、頻寬、能源和功耗。

《從頭重新改造計算方法》

這本具有開創性的書籍以彩色豐富的插圖呈現，代表了自動執行計算方式的根本性變革。它展示了這種新方法如何解決工程師和科學家數十年來一直困擾著他們的問題，包括那些過去只能進行串行處理的問題。

《適合任何使用電腦進行計算的人》

這本書對於任何使用電腦進行技術計算的人都是易於理解的，其中大部分內容只需要高中數學知識。作者通過許多類比使數學變得有趣。他清楚地定義了術語，並使用色彩編碼的方框來表示數學公式、電腦代碼、重要描述和練習題。
