    About stdlib...
  </summary>
  <p>We believe in a future in which the web is a preferred environment for numerical computation. To help realize this future, we've built stdlib. stdlib is a standard library, with an emphasis on numerical and scientific computation, written in JavaScript (and C) for execution in browsers and in Node.js.</p>
  <p>The library is fully decomposable, being architected in such a way that you can swap out and mix and match APIs and functionality to cater to your exact preferences and use cases.</p>
  <p>When you use stdlib, you can be absolutely certain that you are using the most thorough, rigorous, well-written, studied, documented, tested, measured, and high-quality code out there.</p>
  <p>To join us in bringing numerical computing to the web, get started by checking us out on <a href="https://github.com/stdlib-js/stdlib">GitHub</a>, and please consider <a href="https://opencollective.com/stdlib">financially supporting stdlib</a>. We greatly appreciate your continued support!</p>

> Test if a value is a cube number.

<section class="intro">

A **cube number** is defined as an integer value which is the cube of an integer.

</section>

<!-- /.intro -->

<section class="installation">

## Installation

```bash
npm install @stdlib/assert-is-cube-number
```

</section>

<section class="usage">

## Usage

```javascript
var isCubeNumber = require( '@stdlib/assert-is-cube-number' );
```

#### isCubeNumber( value )

Tests if a `value` is a cube number.

<!-- eslint-disable no-new-wrappers -->

```javascript
var Number = require( '@stdlib/number-ctor' );

var bool = isCubeNumber( 8.0 );
// returns true

bool = isCubeNumber( new Number( 8.0 ) );
// returns true

bool = isCubeNumber( 3.14 );
// returns false

bool = isCubeNumber( -5.0 );
// returns false

bool = isCubeNumber( NaN );
// returns false

bool = isCubeNumber( null );
// returns false
```

#### isCubeNumber.isPrimitive( value )

Tests if a `value` is a primitive cube number.

<!-- eslint-disable no-new-wrappers -->

```javascript
var Number = require( '@stdlib/number-ctor' );

var bool = isCubeNumber.isPrimitive( 8.0 );
// returns true

bool = isCubeNumber.isPrimitive( new Number( 8.0 ) );
// returns false
```

#### isCubeNumber.isObject( value )

Tests if a `value` is a `Number` object having a value which is a cube number.

<!-- eslint-disable no-new-wrappers -->

```javascript
var Number = require( '@stdlib/number-ctor' );

var bool = isCubeNumber.isObject( 8.0 );
// returns false

bool = isCubeNumber.isObject( new Number( 8.0 ) );
// returns true
```

</section>

<!-- /.usage -->

<section class="examples">

## Examples

<!-- eslint-disable no-new-wrappers -->

<!-- eslint no-undef: "error" -->

```javascript
var Number = require( '@stdlib/number-ctor' );
var isCubeNumber = require( '@stdlib/assert-is-cube-number' );

var bool = isCubeNumber( 8.0 );
// returns true

bool = isCubeNumber( new Number( 8.0 ) );
// returns true

bool = isCubeNumber( 0.0 );
// returns true

bool = isCubeNumber( 1.0 );
// returns true

bool = isCubeNumber( 3.14 );
// returns false

bool = isCubeNumber( -5.0 );
// returns false

bool = isCubeNumber( NaN );
// returns false

bool = isCubeNumber( '0.5' );
// returns false

bool = isCubeNumber( null );
// returns false
```
