# Modulo

## Overview

![The Modulo Node.](https://1582035224-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2F-MIspkFTPkuGkv4UgQGs-3848250649%2Fuploads%2Fgit-blob-7c1e25e3923fd693ab719cda068e969e4cf97c53%2Fnode-modulo.png?alt=media)

**Modulo** is a *modular arithmetic* **Node**, which divides one number (*dividend*) by a second number (*divisor*) and outputs the *remainder* of the *Euclidean division* operation.

This is the equivalent of the modulo (`%`) operation in computer science.

| `Data Type`        | **Drop-down**                                 | The type of data that will be plugged into the `Input` **Sockets**.                                                                   |
| `Default Dividend` | *Defined in the `Data Type`* ***Attribute***. | The left side of the *Euclidean division* operation (the number to be divided), if no value is provided in the `Dividend` **Socket**. |
| `Default Divisor`  | *Defined in the `Data Type`* ***Attribute***. | The right side of the *Euclidean division* operation (the number to divide by), if no value is provided in the `Divisor` **Socket**.  |

## Inputs

| Input             | Type                                          | Description                                                                     |
| ----------------- | --------------------------------------------- | ------------------------------------------------------------------------------- |
| *Pulse Input* (►) | **Pulse**                                     | A standard input **Pulse**, to trigger the execution of the **Node**.           |
| `Dividend`        | *Defined in the `Data Type`* ***Attribute***. | The left side of the *Euclidean division* operation (the number to be divided). |
| `Divisor`         | *Defined in the `Data Type`* ***Attribute***. | The right side of the *Euclidean division* operation (the number to divide by). |

## 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. |
| `Remainder`        | *Defined in the `Data Type`* ***Attribute**.* | The remainder of the *Euclidean division* operation.                                                                                   |
