    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>

```

</section>

<section class="usage">

## Usage

```javascript
var enum2str = require( '@stdlib/stats-base-ztest-alternative-enum2str' );
```

#### enum2str( value )

Returns the Z-test alternative hypothesis string associated with a Z-test alternative hypothesis enumeration constant.

```javascript
var str2enum = require( '@stdlib/stats-base-ztest-alternative-str2enum' );

var v = str2enum( 'two-sided' );
// returns <number>

var s = enum2str( v );
// returns 'two-sided'
```

If unable to resolve a Z-test alternative hypothesis string, the function returns `null`.

```javascript
var v = enum2str( -999999999 );
// returns null
```
