推荐理由

Stephan T Lavavej also had a surprisingly fun and approachable talk on that problem

说明

这是2019年由CppCon发布的一部演讲，主题归在C, C++, Rust, Go & systems languages。它讲的是floating-point string conversion这一支里的具体问题，而不是把整个领域扫一遍。适合已经能看懂基本术语、想继续往下走的人。内容上可以概括成：Stephan T. Lavavej's CppCon 2019 talk on implementing floating-point to_chars and from_chars in Microsoft's C++ STL. It covers the history of float-string conversion and the algorithms that make it much faster.这些读者给出的理由，核心是：HN calls it a surprisingly fun, approachable talk on a hard problem and cites it in floating-point threads.讲法不绑某一条新闻，过几年仍然可以当材料看。从2020年到2022年，有3位不同的读者在3个不同月份把它推荐出来，其中明确叫别人去看的有1次。适合一次性看完。讲者把一个判断讲透，演示是在给这个判断配例子。如果已经会了基本定义，就把注意力放在它怎么把floating-point string conversion变成能跟着复述的例子。
