    About stdlib...
  </summary>
  <p>We believe in a future in which the web is a preferred environment for numerical computation. To help realize this future, we've built stdlib. stdlib is a standard library, with an emphasis on numerical and scientific computation, written in JavaScript (and C) for execution in browsers and in Node.js.</p>
  <p>The library is fully decomposable, being architected in such a way that you can swap out and mix and match APIs and functionality to cater to your exact preferences and use cases.</p>
  <p>When you use stdlib, you can be absolutely certain that you are using the most thorough, rigorous, well-written, studied, documented, tested, measured, and high-quality code out there.</p>
  <p>To join us in bringing numerical computing to the web, get started by checking us out on <a href="https://github.com/stdlib-js/stdlib">GitHub</a>, and please consider <a href="https://opencollective.com/stdlib">financially supporting stdlib</a>. We greatly appreciate your continued support!</p>

## Installation

```

</section>

<section class="usage">

## Usage

```javascript
var scalar2ndarray = require( '@stdlib/ndarray-base-from-scalar' );
```

#### scalar2ndarray( value, dtype, order )

Returns a zero-dimensional [ndarray][@stdlib/ndarray/base/ctor] containing a provided scalar `value` and having a specified [data type][@stdlib/ndarray/dtypes].

```javascript
var getShape = require( '@stdlib/ndarray-shape' );
var getDType = require( '@stdlib/ndarray-dtype' );

var x = scalar2ndarray( 1.0, 'float64', 'row-major' );
// returns <ndarray>

var sh = getShape( x );
// returns []

var dt = String( getDType( x ) );
// returns 'float64'

var v = x.get();
// returns 1.0
```

<section class="notes">

## Notes

-   If `value` is a number and [`dtype`][@stdlib/ndarray/dtypes] is a complex [data type][@stdlib/ndarray/dtypes], the function returns a zero-dimensional [ndarray][@stdlib/ndarray/base/ctor] containing a complex number whose real component equals the provided scalar `value` and whose imaginary component is zero.

## Examples

<!-- eslint no-undef: "error" -->

```javascript
var dtypes = require( '@stdlib/ndarray-dtypes' );
var scalar2ndarray = require( '@stdlib/ndarray-base-from-scalar' );

// Get a list of data types:
var dt = dtypes( 'integer_and_generic' );

// Generate zero-dimensional arrays...
var x;
var i;
for ( i = 0; i < dt.length; i++ ) {
    x = scalar2ndarray( i, dt[ i ], 'row-major' );
    console.log( x.get() );
}
