# Floor

> Use the Sigma Floor function to round the input number up to the closest multiple of equal or lesser value.

The **Floor** function rounds the input number up to the closest multiple of equal or lesser value.

Note that you may have unexpected rounding results when applying **Floor** to float data types; this behavior depends on how the underlying data warehouse calculates the function.

## Syntax

```sigma
Floor(number, factor)
```

The function has these arguments:

<dl>
  <dt>
    number
  </dt>

  <dd>
    Required
  </dd>

  <dd>
    The number or column of numbers to apply the function.
  </dd>

  <dd>
    Note you may have unexpected results when using floating numbers, depending on the underlying database
  </dd>

  <dt>
    factor
  </dt>

  <dd>
    Optional
  </dd>

  <dd>
    The multiple to apply to the Floor function. The direction of rounding is opposite that of the positive or negative sign of the factor. The factor cannot be 0.
  </dd>

  <dd>
    Default is 1.
  </dd>
</dl>

> **Info**
>
> The Floor function may return unexpected results if the input column is coming from float data type.

## Example

```sigma
Floor(3.6)
```

* Returns 3.

```sigma
Floor(-3.2)
```

* Returns -4.

```sigma
Floor(Cost])
```

* Returns the **Floor** for each row in the input column.

```sigma
Floor([Cost], 0.5)
```

* Returns the **Floor** at a factor of 0.5 for each row in the input column.

```sigma
Floor([Cost], -0.25)
```

* Returns the **Floor** at a factor of -0.25 for each row in the input column.

```sigma
Floor([Cost], 2)
```

* Returns the **Floor** at a factor of 2 for each row in the input column.
