Briefly i want to mention the sas floor and sas ceil functions.
Sas function round floor.
Round function rounds the first argument to the nearest multiple of the second argument or to the nearest integer when the second argument is omitted.
The floor function rounds down.
Testing for approximate equality.
The ceil function rounds up.
For example i would like to round 0 2011 to 202.
Unlike the floorz function the floor function fuzzes the result.
The floorz function does not fuzz the result.
If round x 0 1 round y 0 1 then.
Node 3 of 702.
The floor function returns the largest integer that is less or equal to the argument.
Utility of sas floor and sas ceil functions.
Sas has a wide variety of in built functions which help in analysing and processing the data.
More sas statements.
They take the data variables as arguments and return the result which is stored into another variable.
The functions that perform rounding are the same in the data step as in the sas iml language.
In the example round 0 33 0 1 round returns 0 3 and not 3 0 1.
You can round a number up round it down or round it to the nearest integer.
You should not use the round function as a general method to test for approximate equality.
It will be easier to understand their role now that you understood the explanation above about sas round function.
Node 294 of 702.
More sas statements.
Sas functions and call routines by category tree level 3.
Testing for approximate equality.
If your data contain both positive and negative values you can also round numbers toward zero or away from zero.
Round down in sas or floor in sas uses floor function which rounds down the column in sas.
Round up or ceil in sas using ceil function.
Node 293 of 702.
These functions are used as part of the data statements.
Let s see an example of each.
If round x 0 1 round y 0 1 then.
Abs function tree level 3.
Floor function tree level 3.
I ve tried round ceil and floor but i can t seem to get it to round at the decimal level only the integer level.
In the case below it will return 2.
Node 4 of 702.
The round function returns the value that is based on decimal arithmetic even though this value is sometimes not the exact mathematically correct result.
Therefore with the floorz function you might get unexpected results.
Any help would be greatly appreciated.
Floorz function tree level 3.
If the argument is within 1e 12 of an integer the floor function fuzzes the result to be equal to that integer.
I m trying to perform a roundup function to mimic the function in excel where i want to round up to the nearest decimal.
