If the argument s value is within 1e 12 of an integer the function results in that integer.
Floor integer function sas.
The int function returns the integer portion of the argument truncates the decimal portion.
If the value of argument is positive the int function has the same result as the floor function.
The floorz function does not fuzz the result.
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.
Unlike the floorz function the floor function fuzzes the result.
If the value of argument is positive int argument has the same result as floor argument.
The floorz function uses zero fuzzing.
The functions that perform rounding are the same in the data step as in the sas iml language.
Briefly i want to mention the sas floor and sas ceil functions.
The int function rounds towards zero.
In the case below it will return 2.
If the value of argument is negative the int function has the same result as the ceil function.
The floor function rounds down.
In mathematics and computer science the floor function is the function that takes as input a real number and gives as output the greatest integer less than or equal to denoted or similarly the ceiling function maps to the least integer greater than or equal to denoted or.
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.
The floor function returns the largest integer that is less or equal to the argument.
If the argument s value is within 1e 12 of an integer the function results in that integer.
The round function rounds to the nearest integer.
Round treats the rounding unit as a.
If the value of argument is positive the int function has the same result as the floor.
It will be easier to understand their role now that you understood the explanation above about sas round function.
When the rounding unit is the reciprocal of an integer the round function computes the result by dividing by the integer.
Therefore with the floorz function you might get unexpected results.
If sas reads y with a different informat or if a program other than sas reads y then there is no guarantee that the characters 0 3 would produce a value of exactly 3 10.
The int function returns the integer portion of the argument truncates the decimal portion.
The ceil function rounds up.
Utility of sas floor and sas ceil functions.
The floor function fuzzes the results so that if the results are within 1e 12 of an integer the floor function returns that integer.
