The functions that perform rounding are the same in the DATA step as in the SAS/IML language:

1. The FLOOR function rounds down.
2. The CEIL function rounds up.
3. The ROUND function rounds to the nearest integer.
4. The INT function rounds towards zero.

Also, how does round work in SQL? ROUND (expression, [decimal place]) where [decimal place] indicates the number of decimal points returned. A negative number means the rounding will occur to a digit to the left of the decimal point. For example, -1 means the number will be rounded to the nearest tens.

In this manner, how do I truncate decimals in SAS?

The TRUNC function comes to mind.

We can do it in 3 steps:

1. Multiply our number by 10⁴, effectively making the decimals part of a whole number (shifting the decimal point 4 positions to the right).
2. Apply INT() function that truncates the decimal portion, keeping only the whole portion from the previous step.

How do I scan a function in SAS?

How do you truncate a number?

To truncate a number, we miss off digits past a certain point in the number, filling-in zeros if necessary to make the truncated number approximately the same size as the original number. To truncate a number to 1 decimal place, miss off all the digits after the first decimal place.
