How do you round off in SAS?
ROUND is the function name; argument is the numeric value or variable you want to have rounded; and rounding-unit is the unit that you want to result to be rounded to (e.g. 10, 100, 0.1, 0.01, 5, etc.) For example, ROUND(34.58, 0.1) tells SAS to round the number 34.58 to the nearest tenth. SAS will return 34.6.
Does SAS round up or down?
SAS has several ways to round a number to an integer. You can round a number up, round it down, or round it to the nearest integer. If your data contain both positive and negative values, you can also round numbers toward zero, or away from zero.
How do I reduce decimal places in SAS?
Rounding on Decimals In general, the SAS ROUND-function rounds the first argument to the nearest multiple of the second argument. So, if the second argument is 0.1, then SAS rounds to 1 decimal place. If the second argument is 0.01, then SAS round to 2 decimal places, etc.
What is the syntax of round?
Example
| Formula | Description | Result |
|---|---|---|
| =ROUND(-1.475, 2) | Rounds -1.475 to two decimal places | -1.48 |
| =ROUND(21.5, -1) | Rounds 21.5 to one decimal place to the left of the decimal point | 20 |
| =ROUND(626.3,-3) | Rounds 626.3 to the nearest multiple of 1000 | 1000 |
| =ROUND(1.98,-1) | Rounds 1.98 to the nearest multiple of 10 | 0 |
Do loops in SAS?
Iterative DO loops are the simplest form of DO loops that can be executed within a SAS Data Step. The actions of an iterative DO loop are unconditional, meaning that if you define a loop to execute 50 times, it will execute 50 times without stopping (unless an error occurs during processing).
What is Maxdec in SAS?
ID Statement. MAXDEC=number. specifies the maximum number of decimal places to display the statistics in the output.
What is Floor in SAS?
Returns the largest integer less than or equal to a numeric value expression.
When to use the DROP statement in SAS?
If the DROP= data set option is associated with an output data set, SAS does not write the variables to the output data set, but they are available for processing. In DATA steps, the DROP= data set option can apply to both input and output data sets. The DROP statement applies only to output data sets.
What does rounding by definition do in SAS?
Operating Environment Information: The example above was executed in a z/OS environment. If you use other operating environments, the results will be slightly different. Rounding by definition finds an exact multiple of the rounding unit that is closest to the value to be rounded.
Can you list variables in a data set in SAS?
You can list the variables in any form that SAS allows. If the option is associated with an input data set, the variables are not available for processing. If the DROP= data set option is associated with an output data set, SAS does not write the variables to the output data set, but they are available for processing.
When to use DROP statement in PROC steps?
In DATA steps, when you create multiple output data sets, use the DROP= data set option to write different variables to different data sets. The DROP statement applies to all output data sets. In PROC steps, you can use only the DROP= data set option, not the DROP statement.
