I think we have plenty of evidence that misunderstandings about floating point lead to bugs. For example: https://www.theinquirer.net/inquirer/news/1047844/floating-point-bugs-explode <https://www.theinquirer.net/inquirer/news/1047844/floating-point-bugs-explode> It took me about 30 seconds to find a clear example for floating point, and we all know there are many many more. Can anyone find even a single example of this function leading to a shipping bug in the real world?
