|
||

> Test if a value is an array-like object containing only finite numbers.
|

|

|
||
|
## Usage
|
||
|
|
||
|
```javascript
|
||
|
var isFiniteArray = require( '@stdlib/assert/is-finite-array' );
|
||
|
```
|
||
|
|
||
|
#### isFiniteArray( value )
|
||
|
|
||
|
Tests if a `value` is an array-like object containing **only** finite `numbers`.
|
||
|
|
||
|
<!-- eslint-disable no-new-wrappers -->
|
||
|
|
||
|
```javascript
|
||
|
var Number = require( '@stdlib/number/ctor' );
|
||
|
|
||
|
var bool = isFiniteArray( [ -3.0, new Number(3.0) ] );
|
||
|
// returns true
|
||
|
|
||
|
bool = isFiniteArray( [ -3.0, 'abc' ] );
|
||
|
// returns false
|
||
|
|
||
|
bool = isFiniteArray( [ -3.0, 1.0/0.0 ] );
|
||
|
// returns false
|
||
|
```
|
||
|
|
||
|
#### isFiniteArray.primitives( value )
|
||
|
|
||
|
Tests if a `value` is an array-like object containing **only** primitive finite `numbers`.
|
||
|
|
||
|
<!-- eslint-disable no-new-wrappers -->
|
||
|
|
||
|
```javascript
|
||
|
var Number = require( '@stdlib/number/ctor' );
|
||
|
|
||
|
var bool = isFiniteArray.primitives( [ -1.0, 0.0, 4.5 ] );
|
||
|
// returns true
|
||
|
|
||
|
bool = isFiniteArray.primitives( [ -1.0, 1.0/0.0 ] );
|
||
|
// returns false
|
||
|
|
||
|
bool = isFiniteArray.primitives( [ -3.0, new Number(2.0) ] );
|
||
|
// returns false
|
||
|
```
|
||
|
|
||
|
#### isFiniteArray.objects( value )
|
||
|
|
||
|
Tests if a `value` is an array-like object containing **only** `Number` objects having finite values.
|
||
|
|
||
|
<!-- eslint-disable no-new-wrappers -->
|
||
|
|
||
|
```javascript
|
||
|
var Number = require( '@stdlib/number/ctor' );
|
||
|
|
||
|
var bool = isFiniteArray.objects( [ new Number(-1.0), new Number(2.0) ] );
|
||
|
// returns true
|
||
|
|
||
|
bool = isFiniteArray.objects( [ -1.0, 0.0, 1.0 ] );
|
||
|
// returns false
|
||
|
|
||
|
bool = isFiniteArray.objects( [ -3.0, new Number(1.0) ] );
|
||
|
// returns false
