fix Excel formula problems

Some Windows 10 users encountered an unexpected issue with Microsoft Excel.

When trying to use a formula making different calculations, the error message There’s a problem with this formula disallows the formula function.

This is how one user describes this bug:

I have a simple formula that I have been using for years. Actually, worked until a couple of days ago.  =round((a2/0.25),0)*0.25. This is used to round our retail price to the nearest quarter. When I tried to execute this formula now, I get an error window: There’s a problem with this formula.

If you’re looking for a way around this issue, follow the solutions below.
