# isPrime

> Test if a value is a prime number.

<section class="intro">

A **prime number** is defined as an integer value greater than `1` which is only divisible by `1` and itself.

</section>

<!-- /.intro -->

<section class="usage">

## Usage

```javascript
var isPrime = require( '@stdlib/assert/is-prime' );
```

#### isPrime( value )

Tests if a `value` is a prime number.

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

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

var bool = isPrime( 5.0 );
// returns true

bool = isPrime( new Number( 5.0 ) );
// returns true

bool = isPrime( 3.14 );
// returns false

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

bool = isPrime( NaN );
// returns false

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

#### isPrime.isPrimitive( value )

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

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

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

var bool = isPrime.isPrimitive( 5.0 );
// returns true

bool = isPrime.isPrimitive( new Number( 5.0 ) );
// returns false
```

#### isPrime.isObject( value )

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

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

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

var bool = isPrime.isObject( 5.0 );
// returns false

bool = isPrime.isObject( new Number( 5.0 ) );
// returns true
```

## Examples

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

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

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

var bool = isPrime( 5.0 );
// returns true

bool = isPrime( new Number( 5.0 ) );
// returns true

bool = isPrime( 11.0 );
// returns true

bool = isPrime( 2.0 );
// returns true

bool = isPrime( 3.14 );
// returns false

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

bool = isPrime( NaN );
// returns false

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

bool = isPrime( null );
// returns false
