What happens if the second argument of ROUND is not used?

When the second argument of the ROUND function is not specified, the function defaults to rounding the number to the nearest integer, which corresponds to position 0. This means that if a user calls the ROUND function with only the first argument (the number to be rounded), the result is the number rounded to the nearest whole number.

This behavior is standard in many programming languages and functions that involve rounding. By defaulting to zero decimal places, the ROUND function provides a straightforward way to simplify numerical values without requiring additional input parameters. Therefore, understanding this default behavior is essential for effective use of the ROUND function in NetSuite and similar applications.
