If the square root is 338 and I'm asked to round to the nearest thousandth, how is the answer 18.385? I don't understand how to formulate that answer?

sqrt 338 = 18.384776 on my calculator.
Rounding to the thousandths place is the 3rd place to the right of the decimal which is the 4. The next number to the right is a 7 which is over 5 so 4 is raised to the next number higher and the answer is 18.385
