What Excel function is used to round up to the next whole number when calculating the number of employees needed?

The function used to round up to the next whole number is ROUNDUP. This function will always round any positive number up to the nearest integer, regardless of its decimal component. For example, if you have a calculation that yields a non-integer result, such as 5.3, using the ROUNDUP function will effectively give you 6.

This is especially useful in scenarios like calculating the number of employees needed, where having a fraction of an employee doesn’t make practical sense. By using ROUNDUP, you ensure that you account for the full number of employees required, rather than rounding down and potentially understaffing.

Other functions like ROUND simply round to the nearest integer based on standard rounding rules, while the CEILING function rounds numbers up to the nearest specified multiple. RANDBETWEEN generates random integers within a specified range and does not serve the purpose of rounding numbers. Thus, ROUNDUP is the most appropriate choice for guaranteeing that you round up to the nearest whole number.
