# isNegativeFinite

> Test if a value is a number having a finite negative value.
<section class="usage">

## Usage

```javascript
var isNegativeFinite = require( '@stdlib/assert/is-negative-finite' );
```

#### isNegativeFinite( value )

Tests if a `value` is a `number` having a finite negative value.

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

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

var bool = isNegativeFinite( -5.0 );
// returns true

bool = isNegativeFinite( new Number( -5.0 ) );
// returns true

bool = isNegativeFinite( -3.14 );
// returns true

bool = isNegativeFinite( 5.0 );
// returns false

bool = isNegativeFinite( null );
// returns false

bool = isNegativeFinite( Number.NEGATIVE_INFINITY );
// returns false
```

#### isNegativeFinite.isPrimitive( value )

Tests if a `value` is a primitive `number` having a finite negative value.

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

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

var bool = isNegativeFinite.isPrimitive( -3.0 );
// returns true

bool = isNegativeFinite.isPrimitive( new Number( -3.0 ) );
// returns false
```

#### isNegativeFinite.isObject( value )

Tests if a `value` is a `Number` object having a finite negative value.

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

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

var bool = isNegativeFinite.isObject( -3.0 );
// returns false

bool = isNegativeFinite.isObject( new Number( -3.0 ) );
// 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 isNegativeFinite = require( '@stdlib/assert/is-negative-finite' );

var bool = isNegativeFinite( -5.0 );
// returns true

bool = isNegativeFinite( new Number( -5.0 ) );
// returns true

bool = isNegativeFinite( -3.14 );
// returns true

bool = isNegativeFinite( 0.0 );
// returns false

bool = isNegativeFinite( 5.0 );
// returns false

bool = isNegativeFinite( '-5' );
// returns false

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