Excel

Content will be available soon, but as a teasing starter you can create a new Excel spreadsheet and enter the following numbers and formulas (stated below in European format) in your sheet.

Cell A1 value = 1000,8 (US format would be 1000.8)

Cell A2 value = 1000

Cell A3 formula = A1 - A2

Cell A4 formula = IF(A3>=0,8;"OK";"WRONG") (Dutch: replace IF with ALS)

What is the text you expect cell A4 to display?

What is the text cell A4 actually displays?

This is spooky, don't you think, what went WRONG?

Are you sure your spreadsheets are 100% OK?
