Functions and CALL Routines |
Returns the smallest integer that is greater than or equal to
the argument, using zero fuzzing.
-
argument
-
is a numeric constant, variable, or expression.
Unlike the CEIL function, the CEILZ function
uses zero fuzzing. If the argument is within 1E-12 of an integer, the CEIL
function fuzzes the result to be equal to that integer. The CEILZ function
does not fuzz the result. Therefore, with the CEILZ function you might get
unexpected results.
The following SAS statements produce these results.
