# Negate

## Overview

![The Negate Node.](https://879976444-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2F-MIspkFTPkuGkv4UgQGs-41739140%2Fuploads%2Fgit-blob-39650b5325f3046158e16b7d8d10160cea7c51b6%2Fnode-negate.png?alt=media)

**Negate** is a *logical operator* **Node** which takes a single **Boolean** expression to yield a **Boolean** value, which is the opposite of its input. This is used to mean *NOT* and is the equivalent of the `!` operator in computer programming.

| Input | Output |
| ----- | ------ |
| True  | False  |
| False | True   |

## Inputs

| Input             | Type      | Description                                                           |
| ----------------- | --------- | --------------------------------------------------------------------- |
| *Pulse Input* (►) | **Pulse** | A standard input **Pulse**, to trigger the execution of the **Node**. |
| `Input`           | **Bool**  | The **Boolean** value to be negated.                                  |

## Outputs

| Output             | Type      | Description                                                                                                                          |
| ------------------ | --------- | ------------------------------------------------------------------------------------------------------------------------------------ |
| *Pulse Output* (►) | **Pulse** | A standard output **Pulse**, to move onto the next **Node** along the *logic branch*, once this **Node** has finished its execution. |
| `Output`           | **Bool**  | *true* if `Input` is *false* or *false* if `Input` is *true*.                                                                        |
