Pretty good. A few improvements can be made, but really good. Maybe a more detailed walkthrough would be nice.

This website has errors on it.

"If the previous number is greater than 4 (5,6,7,8,9) round up and add 1" WRONG! The next number is what determines if the number gets rounded up or not.

Furthermore, 589.385 rounded to the nearest hundredth is 589.39, NOT 589.38. Check it on the calculator. The computer got it wrong.
