Office 365 - Excel - Bug - Addition + substraction

Hello,

I found a bug in the Substraction and addition functionality. The bug is really easy to reproduce.

I have a cell with a number, lets say 10 and I substract a number from another cell, lets say 0,1. When I am prolonging the table Excel is getting later on an round error in the number, I guess about position 14 after the point.

This was pretty problematic in my case because the matching does not work anymore.

Sincerely yours

Laurent
