In calculating sales tax. Sales tax is rarely given as a whole number and is more often several decimal places long (e.g., 8.325%). Since any calculation performed with such a number is likely to have at least as many decimal places, the tax is rounded UP and added to the original total.

When I shop I use rounding all the time and estimate the cost of things. That way I know if I have enough money to buy what I have in my cart. This works well and I am usually within a dollar or two of how much I am spending. Try it.

You will use the numbers pi and e (or applications which use them).
In most of the world, these are the numbers which you would use in daily life.
