# Negate

## Overview

![The Negate Node.](/files/MudVwTF25kA3whtisXsd)

**Negate** is a *logical operator* **Node**, which takes a single **Boolean** expression to yield its opposite **Boolean** value.

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*.                                                                          |
