Syntax

FLOOR ( numeric_expression )

Arguments

numeric_expression

An expression of the exact numeric or approximate numeric data type category.

Return types

The return type depends on the input type of numeric_expression:

Input type Return type
float, real float
decimal(p, s) decimal(p, 0)
int, smallint, tinyint int
bigint bigint
money, smallmoney money
bit float

If the result doesn't fit in the return type, an arithmetic overflow error occurs.

For more information, see Precision, scale, and length.

Examples

The following example shows positive numeric, negative numeric, and currency values with the FLOOR function.

SELECT FLOOR(123.45),
       FLOOR(-123.45),
       FLOOR($123.45);

The result is the integer part of the calculated value in the same data type as numeric_expression.
