FLOOR function - Amazon Redshift

FLOOR function

The FLOOR function rounds a number down to the next whole number.


FLOOR (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

FLOOR returns 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.
