What function would you use for rounding numbers in a spreadsheet?

The function that would be used for rounding numbers in a spreadsheet is ROUND(). This function takes a number and an integer, specifying the number of digits to which you want to round the number. If you want to round to the nearest whole number, you would use ROUND(number, 0). Similarly, if you wanted to round to one decimal place, you would set the second argument to 1. This flexibility makes ROUND() a versatile choice for various rounding needs in spreadsheet modeling.

Other options like ROUNDUP() and TRUNC() serve specific purposes; ROUNDUP() always rounds a number up, away from zero, which may not be suitable if standard rounding behavior is desired. TRUNC() simply cuts off digits without rounding, which can lead to different results. Meanwhile, RND() generates a random number but does not perform any rounding functions at all. Therefore, ROUND() is the most appropriate choice for general rounding tasks in spreadsheets.
