## Usage
|
||
|
|
|
||
|
|
```javascript
|
||
|
|
var isFloat64ndarrayLike = require( '@stdlib/assert/is-float64ndarray-like' );
|
||
|
|
```
|
||
|
|
|
||
|
|
#### isFloat64ndarrayLike( value )
|
||
|
|
|
||
|
|
Tests if a value is an [ndarray][@stdlib/ndarray/ctor]-like object whose underlying data type is `float64`.
|
||
|
|
|
||
|
|
```javascript
|
||
|
|
var Float64Array = require( '@stdlib/array/float64' );
|
||
|
|
var ndarray = require( '@stdlib/ndarray/ctor' );
|
||
|
|
|
||
|
|
var arr = ndarray( 'float64', new Float64Array( [ 0, 0, 0, 0 ] ), [ 2, 2 ], [ 2, 1 ], 0, 'row-major' );
|
||
|
|
|
||
|
|
var bool = isFloat64ndarrayLike( arr );
|
||
|
|
// returns true
|
||
|
|
```
