I am reminded of about 1992, when the 486 Intel microprocessor was discovered to have a rather serious flaw in its arithmetic unit, with potential errors in the 4th and even the 3rd digit. Intel ended up replacing those CPU's. I wonder if they will do the same thing this time.This particular article https://www.nytimes.com/1994/11/24/business/company-news-flaw-undermines-accuracy-of-pentium-chips.html mentions the Pentium and 1994, but I believe that the 486 had a similar problem. But I am unable to find reference to it. Also: https://www.cs.earlham.edu/~dusko/cs63/fdiv.html https://www.computerworld.com/article/2515483/epic-failures-11-infamous-software-bugs.html?page=3
