# isSquareNumber

> Test if a value is a square number.

<section class="intro">

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

</section>

<!-- /.intro -->

<section class="usage">

## Usage

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

#### isSquareNumber( value )

Tests if a `value` is a square number.

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

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

var bool = isSquareNumber( 4.0 );
// returns true

bool = isSquareNumber( new Number( 4.0 ) );
// returns true

bool = isSquareNumber( 3.14 );
// returns false

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

bool = isSquareNumber( NaN );
// returns false

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

#### isSquareNumber.isPrimitive( value )

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

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

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

var bool = isSquareNumber.isPrimitive( 4.0 );
// returns true

bool = isSquareNumber.isPrimitive( new Number( 4.0 ) );
// returns false
```

#### isSquareNumber.isObject( value )

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

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

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

var bool = isSquareNumber.isObject( 4.0 );
// returns false

bool = isSquareNumber.isObject( new Number( 4.0 ) );
// returns true
```

## Examples

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

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

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

var bool = isSquareNumber( 4.0 );
// returns true

bool = isSquareNumber( new Number( 4.0 ) );
// returns true

bool = isSquareNumber( 0.0 );
// returns true

bool = isSquareNumber( 1.0 );
// returns true

bool = isSquareNumber( 3.14 );
// returns false

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

bool = isSquareNumber( NaN );
// returns false

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

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