What does the ROUND(12.67, 1) function return?

The ROUND function in NetSuite, like many programming and database environments, is used to round a number to a specified number of decimal places. In the case of the ROUND(12.67, 1), the function is set to round the number 12.67 to one decimal place.

When rounding a number, you look at the digit immediately to the right of the desired decimal place to determine if you need to round up or down. In this instance, the number 12.67 has a "6" in the tenths place (1 decimal place) and a "7" in the hundredths place (2 decimal places). Since the hundredths place (7) is greater than 5, the rounding rule indicates that we round up the tenths place from 6 to 7.

Consequently, the result is 12.7, which accurately reflects the expected outcome of the rounding operation. This understanding of rounding rules confirms the selection of the correct answer.
