If you are interested in the human side of the discussion of error, I'd suggest taking a look at chapter 4 of Otte and Mlynarczyk's 2010 book on Basic Writing and Stuart Moultrhop's essay "Error 1337" in the collection edited by Mark Nunes entitled "Error: Glitch, Noise, and Jam in New Media" (Bloomsbury, 2010). For a 19th c. perspective, you might want to take a look at Kuno Fischer's chapter on "The Origin of Error" in his History of Modern Philosophy (1854–77; the link is to an 1887 English translation).All best,JohannahOn Sat, Jul 4, 2020 at 10:04 AM Richard Vahrenkamp <vahrenkamp2@gmx.de> wrote:_______________________________________________Although physicists often use rules of thumb, the precision of calculation became an important point in John von Neumann's policy against the analogue computer. The precision of individual calculations on analog machines is lower than on digital machines. But the final results of integrating a differential equation were the same on analog machines as on digital ones, as comparisons in the 1950s showed, see my paper The Computing Boom in the US Aeronautical Industry, 1945–1965, in: ICON – The Journal of the International Committee for the History of Technology, volume 24, 2019, pp. 127–149.

Rounding error is ubiquitous and unavoidable in digital computers, but with high precision computing (64-bit, 128-bit) it’s so small as to be negligible. However, in cases where the same computation is performed many thousands or millions of times, it can still accumulate to a point that it’s significant. MacKenzie, D. (1993). Negotiating Arithmetic, Constructing Proof: The Sociology of Mathematics and Information Technology. Social Studies of Science, 23(1), 37-65. Also see the short examples of this in my book A Vast Machine: Computer Models, Climate Data, and the Politics of Global Warming (MIT Press, 2010), pages 177-178.

My sense is that actual, literal (mathematical) mistakes in modern computers are quite rare; the notorious Pentium bug of the early 1990s is the exception that proves the rule. Most bugs are, rather, code proceeding to a perfectly correct logical outcome that just so happens to be inimical or intractable to the user and/or other dependent elements of the system. The Y2K "bug," for instance, was actually code executing in ways that were entirely internally self-consistent, however much havoc the code would wreak (or was expected to wreak). Can anyone recommend reading that will help me formulate such thoughts with greater confidence and accuracy? Or serve as a corrective? I'd like to read something fundamental and even philosophical about, as my subject line has it, the nature of computational error. I'd also be interested in collecting other instances comparable to the Pentium bug--bugs that were actual flaws and mistakes hardwired at the deepest levels of a system.
