|
## Usage
|
|
|
|
```javascript
|
|
var isNegativeNumberArray = require( '@stdlib/assert/is-negative-number-array' );
|
|
```
|
|
|
|
#### isNegativeNumberArray( value )
|
|
|
|
Tests if a `value` is an array-like object containing **only** negative numbers.
|
|
|
|
<!-- eslint-disable no-new-wrappers -->
|
|
|
|
```javascript
|
|
var Number = require( '@stdlib/number/ctor' );
|
|
|
|
var bool = isNegativeNumberArray( [ -3.0, new Number(-3.0) ] );
|
|
// returns true
|
|
|
|
bool = isNegativeNumberArray( [ -3.0, '-3.0' ] );
|
|
// returns false
|
|
```
|
|
|
|
#### isNegativeNumberArray.primitives( value )
|
|
|
|
Tests if a `value` is an array-like object `array` containing **only** primitive negative numbers.
|
|
|
|
<!-- eslint-disable no-new-wrappers -->
|
|
|
|
```javascript
|
|
var Number = require( '@stdlib/number/ctor' );
|
|
|
|
var bool = isNegativeNumberArray.primitives( [ -1.0, -5.0, -10.0 ] );
|
|
// returns true
|
|
|
|
bool = isNegativeNumberArray.primitives( [ -3.0, new Number(-1.0) ] );
|
|
// returns false
|
|
```
|
|
|
|
#### isNegativeNumberArray.objects( value )
|
|
|
|
Tests if a `value` is an array-like object `array` containing **only** object negative numbers.
|
|
|
|

|
|
|
|
```javascript

var bool = isNegativeNumberArray.objects( [ new Number(-1.0), new Number(-1.0) ] );
|
|
// returns true
|
