Description The following is copied with extra bits from https://aka.ms/AAwwjwl (Feedback Hub) to raise awareness of this issue: Hello, I'm a contributor to osu! (https://github.com/ppy/osu). A user reported a really weird problem with our game that only happens in the current version of Canary (27881.1000) in ppy/osu#33948. I've narrowed it down to ppy/osu#33948 (comment), which is Math.Pow(-1, 2) returning -1 instead of 1 for some odd reason. Used VSCode for C# installation of .NET 8 (what osu! uses). I've also tried the same math function in Python, but the value was correct (1). C++'s std::pow(-1,2) seems to also output -1, so it may be a bigger issue in Windows. If you need to contact us better, joining the osu! Discord server would be best (https://discord.gg/ppy). Reproduction Steps Console . WriteLine ( Math . Pow ( - 1 , 2 ) ) ; or std::cout << std::pow(- 1 , 2 ) << std::endl; Expected behavior It should output 1. Actual behavior It outputs -1 on Windows 11 Insider Preview, Canary channel (27881.1000).
