Floor Integer Function Sas

When the rounding unit is the reciprocal of an integer the round function computes the result by dividing by the integer.

Floor integer function sas.

If the value of argument is positive the int function has the same result as the floor function. The floor function rounds down. If the argument s value is within 1e 12 of an integer the function results in that integer. The ceil function rounds up.

If the value of argument is positive the int function has the same result as the floor function. If the value of argument is positive int argument has the same result as floor argument. 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.

In the case below it will return 2. The floor function returns the largest integer that is less or equal to the argument. 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 value of argument is negative the int function has the same result as the ceil function.

It will be easier to understand their role now that you understood the explanation above about sas round function. The int function returns the integer portion of the argument truncates the decimal portion. If the argument s value is within 1e 12 of an integer the function results in that integer. If the argument s value is within 1e 12 of an integer the function results in that integer.

Therefore with the floorz function you might get unexpected results. If the argument is within 1e 12 of an integer the floor function fuzzes the result to be equal to that integer. For example and while. The functions that perform rounding are the same in the data step as in the sas iml language.

The int function rounds towards zero. If the value of argument is positive the int function has the same result as the floor. The floorz function does not fuzz the result. The round function rounds to the nearest integer.

If the argument s value is within 10 12 of an integer the function results in that integer. 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. Unlike the floorz function the floor function fuzzes the result. Utility of sas floor and sas ceil functions.

Therefore with the floorz function you might get unexpected results. The floorz function uses zero fuzzing.
