| Functions and CALL Routines |
Returns the smallest integer that is greater than or equal to
the argument, fuzzed to avoid unexpected floating-point results
-
argument
-
is numeric.
If the argument is within 1E-12 of an
integer, the function returns that integer.
Unlike the CEILZ function, the CEIL function fuzzes the
result. 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.
