Thanks Jeff, for your customary focused, useful style and content!

Your article points out a secondary annoyance here in SQL: the ROUND() function returns a value of the same type as its passed argument. In your examples under "Incorrect Rounding", note that all of the returned values using ROUND(SomeNumber, 2) return 3 decimals.

In junior high school, if I answered the test question "Round off 0.325 to 2 decimal places" with "0.330" I would have gotten that one wrong. Significant digits? What's that? That trailing zero means something in science, and its inclusion here is, IMHO, incorrect. The correct answer is 0.33.

Any thoughts on this?
