  • 在这个背景下,我也强烈推荐约翰·古斯塔夫森的书《误差的终结》(The End of Error)。里面全是绝佳的例子,有处地方还将数值计算的进展与其他领域的改进做了对比:“在1970年,一台打印机打印出来的东西可能是这个样子的,需要耗时……

    In this context, I also highly recommend John Gustafson's book, The End of Error. It is full of great examples, and at one point contrasts advances in numerical computing with improvements in other areas: "In 1970, a printer might produce something that looks like this, and take…

  • 说到浮点数(floats),我强烈推荐约翰·古斯塔夫森的书《误差的终结:Unum计算》:https://www.crcpress.com/The-End-of-Error-Unum-Computing/Gus... 这是一本惊艳的汇编,列举了浮点数在实际应用中无法提供任何保证的诸多情况。在某些情况下,……

    Speaking of floats, I highly recommend John Gustafson's book, The End of Error: Unum Computing: https://www.crcpress.com/The-End-of-Error-Unum-Computing/Gus... It is an amazing compendium of the many ways in which floats fail to give any guarantees in practice. In some cases,…

  • 我读了约翰·古斯塔夫森的《误差的终结》这本书。他直接在书里解决了大量的数值问题,给出了代码和结果。他还梳理了浮点数和数值计算的历史,强调了往往最优秀的……

    I read the book, the End of Error by John Gustafson. He works on a lot of numerical problems right there, providing code and results. He also goes over the history of floats and numerical computation, highlighting how often the best…

  • 《误差的终结》(http://www.amazon.com/The-End-Error-Computing-Computational/...)是一本极为详尽地描述它们的书……我正在和约翰合作搭建一个公开可访问的 wiki,希望能……

    The End of Error (http://www.amazon.com/The-End-Error-Computing-Computational/...) is the book describing them in great detail... I'm working with John to put together a publicly accessible wiki, which I hope will be…

  • 约翰·古斯塔夫森开发了几种很有前景的替代方案,比如 unums、posits 和 valids:https://posithub.org/about 我还推荐他的书《误差的终结——Unum计算》:https://www.crcpress.com/The-End-of-Error-Unum-Computing/Gus... 他与威廉·卡汉(William Kahan)的辩论实录在这里:http://www.johngustafson.net/pdfs/DebateTranscription.pdf

    John Gustafson has developed several promising alternatives, such as unums, posits and valids: https://posithub.org/about I also recommend his book, The End of Error - Unum Computing: https://www.crcpress.com/The-End-of-Error-Unum-Computing/Gus...
