I have a spreadsheet of banking data, so cannot share as example.

I've been using for years and updating the values every month.

I have a particular cell where I compare a cell value in one sheet with a cell value in another sheet (TRUE/FALSE) and this is suddenly returning a FALSE, where I know that the two values are the same. Both values are SUM functions of other data.

When I expand the number of decimal places of both fields, I notice that there is a 1 at the tenth decimal place in one of the 2 cells being compared. This is unexplained, as I have checked the values underlying the SUM in that cell and there is no 1 at tenth decimal place.

Calculation is turned on
Formatting (number to 2 dp's) is the same

Any ideas as to how to proceed?
