# Is Equal

## Overview

![](/files/yBvyI2qBa0PPyvjOH2an)

**IsEqual** is a **Relational Expression Node**, which compares two **Input Values**, and returns a **Boolean**, based on whether or not they are *equal* to one another.

**Relational Expressions** are frequently used alongside **Branch Nodes** and **Logical Operator Nodes** to manipulate the flow of logic and are essential when building any complex applications.

## Attributes

| Attribute   | Type          | Description                                                             |
| ----------- | ------------- | ----------------------------------------------------------------------- |
| `Data Type` | **Drop-down** | The type of data that will be plugged into the `A` and `B` **Sockets**. |

## 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 **Value** to be compared with `B`.                                |
| `B`               | *Defined in the* `Data Type` ***Attribute**.* | The **Value** to be compared with `A`.                                |

## 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`                | **Bool**  | Returns *true* if `A` is equal to `B`. If not, then it returns *false*.                                                                |

## Examples

Below is an insight into the behaviour of the **IsEqual Node**. Note that when comparing **Strings**, the evaluation of equality is *case-sensitive*.

|             |             |         |
| ----------- | ----------- | ------- |
| `A`         | `B`         | `C`     |
| 123         | 123         | *True*  |
| 85.05       | 85.06       | *False* |
| "Cat"       | "Dog"       | *False* |
| False       | False       | *True*  |
| "Mr. Smith" | "mr. smith" | *False* |
