2. True Story:

When you have money in a savings account, you sometimes get interest (2% or 3%) on your money. That’s the bank’s way of thanking you for investing your money with them. The % interest produces money amounts that are long decimal numbers.

A crooked investment banker decided to round everyone’s account balance down (to the nearest penny), and to pocket the fractions of pennies for himself, in a secret account. He did this once a month, thinking no one would notice.
