# NOT

Changes FALSE to TRUE, or TRUE to FALSE.

## Syntax

```
NOT(<logical>)
```

### Parameters

Term | Definition |
---|---|

logical | A value or expression that can be evaluated to TRUE or FALSE. |

## Return value

TRUE OR FALSE.

## Example

The following example retrieves values from the calculated column that was created to illustrate the IF function. For that example, the calculated column was named using the default name, **Calculated Column1**, and contains the following formula: `=IF([Orders]<300,"true","false")`

The formula checks the value in the column, [Orders], and returns "true" if the number of orders is under 300.

Now create a new calculated column, **Calculated Column2**, and type the following formula.

```
=NOT([CalculatedColumn1])
```

For each row in **Calculated Column1**, the values "true" and "false" are interpreted as the logical values TRUE or FALSE, and the NOT function returns the logical opposite of that value.
