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