# Arc Tangent

## Overview

![The Arc Tangent Node](https://3009747178-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2F-MIspkFTPkuGkv4UgQGs-1330240639%2Fuploads%2Fgit-blob-e56bf19ba0dd977647d13df1ff931600274da530%2Fnode-arc-tangent.png?alt=media)

The **Arc Tangent Node** takes a single **Float** value, representing an angle, in degrees (°) or radians (rad), and returns its *arctangent*.

| --------------- | --------- | -------------------------------------------------------------------------------- |
| `Default Value` | **Float** | The default value of `Input`, if no value is provided in the `Input` **Socket**. |

## Inputs

| Input             | Type      | Description                                                           |
| ----------------- | --------- | --------------------------------------------------------------------- |
| *Pulse Input* (►) | **Pulse** | A standard **Input Pulse**, to trigger the execution of the **Node**. |
| `Input`           | **Float** | The angle to calculate the *arctangent* of.                           |

## Outputs

| ------------------ | --------- | -------------------------------------------------------------------------------------------------------------------------------------- |
| *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`           | **Float** | The *arctangent* of `Input`.                                                                                                           |
