## Usage

```javascript
var defaults = require( '@stdlib/ndarray/defaults' );
```

#### defaults()

Returns default ndarray settings.

```javascript
var out = defaults();
// returns {...}
```

The returned object has the following properties:

-   **dtypes**: default data types.

    -   **default**: default data type.
    -   **numeric**: default numeric data type.
    -   **real**: default real-valued data type.
    -   **floating_point**: default floating-point data type.
    -   **real_floating_point**: default real-valued floating-point data type.
    -   **complex_floating_point**: default complex-valued floating-point data type.
    -   **integer**: default integer data type.
    -   **signed_integer**: default signed integer data type.
    -   **unsigned_integer**: default unsigned integer data type.
    -   **boolean**: default boolean data type.
    -   **index**: default index data type.
    -   **integer_index**: default integer index data type.
    -   **boolean_index**: default boolean index data type.
    -   **mask_index**: default mask index data type.

-   **order**: default memory layout.

-   **casting**: default casting mode.

-   **index_mode**: default index mode.

#### defaults.get( name )

Returns the setting value for a provided setting `name`.

```javascript
var v = defaults.get( 'order' );
// returns <string>

v = defaults.get( 'dtypes.floating_point' );
// returns <string>
```

The setting `name` corresponds to a flattened object path. For example, the setting name `'dtypes.default'` maps to the nested path `o.dtypes.default` as found in the object returned by `defaults()`.

## Examples

```javascript
var array = require( '@stdlib/ndarray/array' );
var defaults = require( '@stdlib/ndarray/defaults' );

var o = defaults();

var buf = [ [ 1, 2 ], [ 3, 4 ] ];
var opts = {
    'order': o.order,
    'casting': 'unsafe',
    'mode': o.index_mode
};

opts.dtype = o.dtypes.default;
var x = array( buf, opts );
console.log( x.dtype );

opts.dtype = o.dtypes.floating_point;
x = array( buf, opts );
console.log( x.dtype );

opts.dtype = o.dtypes.real_floating_point;

opts.dtype = o.dtypes.signed_integer;
x = array( buf, opts );
console.log( x.dtype );

opts.dtype = o.dtypes.unsigned_integer;
x = array( buf, opts );
console.log( x.dtype );

opts.dtype = o.dtypes.boolean;
x = array( buf, opts );
console.log( x.dtype );
```
