However, calculators are usually set up to do math like people (base 10)
while computers are set up to do math . . . well, like computers (base 2).
So unless we want to set the computer up to do base 10 math (BCD, fixed
point bigints, etc), which is slow for a computer, we have to live with
inaccuracies that we humans sometimes have problems understanding :(
