Hi Caroline87sry,
Thanks for providing the example workbook.
I find a strange thing in this workbook, please kindly see the screenshot below:
1. Whatever decimal places settings I set, it only shows the integer number like 6, 5, 10.
2. When I click into the cell, put the mouse after the number, then press “Delete” button to clear something, then the number will show fine with the decimal settings. Then the number can be calculated fine with the formula.
I think, we need to check where the data source is from. I assume the data is not created by typing manually. For example, it is from any data query or something else? If this is the case, we may find the root cause.
Regards,
Rena
