I found what I think is a significant bug in Excel for Mac 16.29.1. I would like to show it to MS. How?
In some cases adding two numbers gives an incorrect result. A digit incorrectly shows up in the 12th decimal position in the result when adding two numbers that are truncated to just two decimal places. The xlsx file attached shows an example. I'm attaching a PDF of the same file to show these results in case another version of Excel gives different results with the xlsx file.
