Anyway, yes, that's all true. Excel, Sheets, JavaScript numbers, Java doubles, Python floats, and so on all work this way. That's why I asked how switching spreadsheet implementations solved the problem.

I agree with you that switching programs that are all using the IEEE floating-point formats with the same underlying hardware implementations should result in the same answers.
