# Modulo

## Overview

![](/files/-MIxaVLJeGfXvxG3ihf4)

**Modulo** takes two **Numerical Type Inputs**; `a` (*the dividend*) and `b` (*the divisor*) and returns the *remainder* of the *division* of `a` and `b`.

Unlike normal division, this kind of operation, actually considers how many times the divisor fits into the dividend in its entirity (the *quotient*), with the *remainder* being the amount that is left over.

## Attributes

| Attribute   | Type                                          | Description                                                                    |
| ----------- | --------------------------------------------- | ------------------------------------------------------------------------------ |
| `Data Type` | *Defined in the* `Data Type` ***Attribute**.* | The **Numerical Data Type** of both the dividend and the divisor (`a` and `b`) |

## Inputs

| Input             | Type                                          | Description                                                           |
| ----------------- | --------------------------------------------- | --------------------------------------------------------------------- |
| *Pulse Input* (►) | **Pulse**                                     | A standard **Input Pulse**, to trigger the execution of the **Node**. |
| `a`               | *Defined in the* `Data Type` ***Attribute**.* | The dividend (number to be divided).                                  |
| `b`               | *Defined in the* `Data Type` ***Attribute**.* | The divisor (amount the dividend should be divided 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. |
| `c`                | *Defined in the* `Data Type` ***Attribute**.* | The remainder of the division operation. (*divisor - dividend \* quotient*).                                                           |
