Computes the largest integer that is not more than the input value. Input can be an Integer, a Decimal, a column reference, or an expression.

## Basic Usage

Numeric literal example:

derive type:single value: FLOOR(2.5)

Output: Generates a column with each row's value `2`.

Expression example:

derive type:single value: FLOOR(MyValue + 2.5)

Output: Generates a column containing the largest integer that is less than the sum of 2.5 and the value in the `MyValue` column.

## Syntax

derive type:single value: FLOOR(numeric_value)

ArgumentRequired?Data TypeDescription
numeric_valueYstring, decimal, or integerName of column or Decimal or Integer literal to apply to the function

For more information on syntax standards, see Language Documentation Syntax Notes.

### numeric_value

Name of the column, numeric literal, or numeric expression.

• Missing input values generate missing results.
• Literal numeric values should not be quoted. Quoted values are treated as strings.
• Multiple columns and wildcards are not supported.

Usage Notes:

Required?Data TypeExample Value
YesString (column reference) or Integer or Decimal literal`2.5`

## Examples

### Example - Exponential functions

The following example demonstrates how the rounding functions work together. These functions include the following:

• `FLOOR` - largest integer that is not greater than the input value. See FLOOR Function.
• `CEILING` - smallest integer that is not less than the input value. See CEILING Function.
• `ROUND` - nearest integer to the input value. See ROUND Function.
• `MOD` - remainder integer when input1 is divided by input2. See Numeric Operators
