It completely screws up numbers if the column is a number and the number is over 15 digits long.

I work in insurance in Brazil, by standards of our regulatory body, claims numbers must be a string of 20 numbers (zfill(20) if needed). You can't imagine the amount of times excel had fucked me up rounding down the claim numbers, this is one of the first things I teach to my interns and juniors when they're working with the claims databases.
