jchd Posted December 20, 2018 Share Posted December 20, 2018 Here's a trivial exemple of some simple computation going awry. The implementation language is mostly irrelevant (here, AutoIt) as you'd get about the same thing with C and the vast majority of languages.

jchd Posted December 20, 2018 Author Share Posted December 20, 2018 You mean using a closed-form direct computation? Yes of course, but that's not always possible and there are no safeguards against a little inconspicious series like the one examplified. In this particular case you can very easily run the loop up to, say, 1000 and decide in good faith that the asymptotical result is indeed 100 without suspecting anything. Well, until the crew sees Jupiter enlarging dangerously fast in their windows. This wonderful site allows debugging and testing regular expressions (many flavors available).
