Round off to decimal places in sas.
Sas function floor int.
Below is a list of types of functions sas provides.
If the value of argument is positive the int function has the same result as the floor function.
Therefore with the floorz function you might get unexpected results.
The following statements evaluate each function on a vector of numbers so that you can observe the different rounding behaviors.
So we will be using cars table in our example.
The following sas statements produce these results.
Round down or floor in sas using floor function.
Round off the column in sas is accomplished by round function.
The general syntax for using a function in sas is as below.
Round down in sas or floor in sas uses floor function which rounds down the column in sas.
Returns the largest integer that is less than or equal to theargument.
If the value of argument is negative the int function has the same result as the ceil function.
The int function returns the integer portion of the argument truncates the decimal portion.
Round off the column in sas using round function.
The int function rounds towards zero.
If the argument s value is within 1e 12 of an integer the function results in that integer.
Depending on their usage the functions in sas are categorised as below.
If the value of argumentis positive int argument has the same result as floor argument.
Returns the integer portion of the argument truncates the decimal portion.
The following example shows positive numeric negative numeric and currency values with the floor function.
Otherwise the argument is converted to double if not so already and the result is double.
Functionname argument1 argument2 argumentn here the argument can be a constant variable expression or another function.
If the result is a number that does not fit into the range of a double the floor function fails.
The floorz function does not fuzz the result.
If the value of argumentis negative int argument.
Round up or ceil in sas using ceil function.
Sas does not have a built in function that rounds away from zero but you can combine the sign function with another function to round away from zero.
The result is the integer part of the calculated value in the same data type as numeric expression.
If the argument s value is within 10 12 of an integer the function results in that integer.
If the value of argument is negative the int function has the same result as the ceil function.
Let s see an example of each.
Select floor 123 45 floor 123 45 floor 123 45.
If the argument is within 1e 12 of an integer the floor function fuzzes the result to be equal to that integer.
If the argument s value is within 1e 12 of an integer the function results in that integer.
If the argument is decimal the result is decimal.
