# isNumberArray
> Test if a value is an array-like object of numbers.
## Usage
```javascript
var isNumberArray = require( '@stdlib/assert/is-number-array' );
```
#### isNumberArray( value )
Tests if a `value` is an array-like object of `numbers`.
```javascript
var bool = isNumberArray( [ 1, 2, 3, 4 ] );
// returns true
```
#### isNumberArray.primitives( value )
Tests if a `value` is an array-like object containing **only** `number` primitives.
```javascript
var Number = require( '@stdlib/number/ctor' );
var bool = isNumberArray.primitives( [ 1, 2, 3 ] );
// returns true
bool = isNumberArray.primitives( [ 1, new Number( 2 ), 3 ] );
// returns false
```
#### isNumberArray.objects( value )
Tests if a `value` is an array-like object containing **only** `Number` objects.
```javascript
var Number = require( '@stdlib/number/ctor' );
var bool = isNumberArray.objects( [ new Number( 1 ), new Number( 2 ) ] );
// returns true
bool = isNumberArray.objects( [ new Number( 1 ), 2 ] );
// returns false
```
## Examples
```javascript
var Number = require( '@stdlib/number/ctor' );
var isNumberArray = require( '@stdlib/assert/is-number-array' );
var bool = isNumberArray( [ 3.14 ] );
// returns true
bool = isNumberArray( [ NaN ] );
// returns true
bool = isNumberArray( [ 1, 2, 3 ] );
// returns true
bool = isNumberArray( [ new Number( 3.14 ), 2, 3 ] );
// returns true
bool = isNumberArray( 3.14 );
// returns false
bool = isNumberArray( [] );
// returns false
bool = isNumberArray( [ '1', 2 ] );
// returns false
```
