CEIL Function

Returns the smallest integer that is greater than or equal to the argument, fuzzed to avoid unexpected floating-point results.

Syntax

CEIL (argument)

Required Argument

argument

specifies a numeric constant, variable, or expression.

Details

If the argument is within 1E-12 of an integer, the function returns that integer.

Comparisons

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.

Example

The following SAS statements produce these results.

a=ceil(var1);
