CEILING
The CEILING function returns the smallest integer value that is greater than or equal to the argument.
The schema is SYSIBM.
The argument must be an expression that returns a value of any built-in numeric data type.
The
argument can also be a character string or graphic string data type.
The string input is implicitly cast to a numeric value of DECFLOAT(34).
The result of the function has the same data type and length attribute as the argument except that the scale is 0 if the argument is DECIMAL. For example, an argument with a data type of DECIMAL(5,5) results in DECIMAL(5,0).
The result can be null; if the argument is null, the result is the null value.
CEIL can be specified as a synonym for CEILING.
Example 1: The following statement shows the use of CEILING on positive and negative
values:
SELECT CEILING(3.5), CEILING(3.1), CEILING(-3.1), CEILING(-3.5)
FROM SYSIBM.SYSDUMMY1;Example 2: Using sample table DSN8A10.EMP,
find the highest monthly salary for all the employees. Round the result
up to the next integer. The SALARY column has a decimal data type.
SELECT CEILING(MAX(SALARY)/12)
FROM DSN8A10.EMP;
