CEILING (or CEIL) function

The CEILING or CEIL function is used to round a number up to the next whole number. (The FLOOR function rounds a number down to the next whole number.)


{CEIL | CEILING}(number)



The number or expression that evaluates to a number. It can be the SMALLINT, INTEGER, BIGINT, DECIMAL, FLOAT4, FLOAT8, or SUPER type.

Return type

CEILING and CEIL return the same data type as its argument.

When the input is of the SUPER type, the output retains the same dynamic type as the input while the static type remains the SUPER type. When the dynamic type of SUPER isn't a number, Amazon Redshift returns a null.


The following example uses the TICKIT sample database. For more information, see Sample database.
