What is the correct syntax to use the round function in SAS?

The round function in SAS is designed to round a given numeric value to a specified unit or multiple. The correct syntax, as illustrated in the chosen answer, is round(value, unit).

In this syntax, "value" represents the numeric value you wish to round, and "unit" is the number to which you want to round the "value." For example, if you have a value of 5.67 and you want to round it to the nearest whole number, you can use the round function as round(5.67, 1). In this case, the "unit" is 1, which means you are rounding to the nearest whole number. If the goal is to round to the nearest 10, you could use round(57, 10), resulting in 60.

Other options do not follow the correct syntax for this function. Using "round(unit, value)" swaps the position of the arguments, which is not how the function is structured. "round(number, multiple" is close but uses the word "number," which is not the standard term used consistently in documentation. Lastly, "round(value, round off unit)" includes unnecessary language that does not conform to the succinct syntax expected in SAS function calls.
