    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>

## Usage

```javascript
var ns = require( '@stdlib/random-array-tools' );
```

#### ns

Namespace containing array creation pseudorandom number generator (PRNG) function tools.

```javascript
var o = ns;
// returns {...}
```

## Examples

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

```javascript
var exponential = require( '@stdlib/random-base-exponential' );
var arcsine = require( '@stdlib/random-base-arcsine' );
var randn = require( '@stdlib/random-base-improved-ziggurat' );
var ns = require( '@stdlib/random-array-tools' );

// Create a binary PRNG array:
var dtypes = [ 'float64', 'float32', 'generic' ];
var defaultDType = 'float64';

var rand = new ns.binary( arcsine, dtypes, defaultDType );
var x = rand.generate( 10, 2.0, 5.0 );
// e.g., returns <Float64Array>[ ~3.65, ~4.34, ~3.52, ~4.68, ~2.62, ... ]

// Create a unary PRNG array:
rand = new ns.unary( exponential, dtypes, defaultDType );
x = rand.generate( 10, 0.5 );
// e.g., returns <Float64Array>[ ~0.22, ~2.89, ~0.69, ~2.48, ~0.82, ... ]

// Create a nullary PRNG array:
rand = new ns.nullary( randn, dtypes, defaultDType );
x = rand.generate( 10 );
// e.g., returns <Float64Array>[ ~-0.22, ~1.89, ~-0.69, ~0.48, ~-0.82, ... ]
