17. Precision in ROUND()
Review and practice



What happens if the second argument in ROUND() is set to anything other than zero?

The second argument specifies the number of decimals to be returned. For example:

SELECT ROUND(136.123, 2);

will return 136.120.

Let's try this out.


Show each character's name, its actual AccountBalance, and the AccountBalance rounded to a single decimal place. Name the column RoundedBalance.

Stuck? Here's a hint!

Here, you'll need ROUND(AccountBalance, 1).
