Syntax

FLOOR ( numeric_expression )  

Arguments

numeric_expression
Is 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(38, s)
int, smallint, tinyint	int
bigint	bigint
money, smallmoney	money
bit	float

If the result does not fit in the return type, an arithmetic overflow error occurs.

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.

---------      ---------     -----------  
123            -124          123.0000
