    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>

# abs

[![NPM version][npm-image]][npm-url] [![Build Status][test-image]][test-url] [![Coverage Status][coverage-image]][coverage-url] <!-- [![dependencies][dependencies-image]][dependencies-url] -->

> Compute the [absolute value][@stdlib/math/base/special/abs] for each element in an input array.

<section class="installation">

## Installation

```bash
npm install @stdlib/math-array-special-abs
```

</section>

<section class="usage">

## Usage

```javascript
var abs = require( '@stdlib/math-array-special-abs' );
```

#### abs( x\[, options] )

Computes the [absolute value][@stdlib/math/base/special/abs] for each element in an input array.

```javascript
var v = abs( [ -1.0, 2.0, -3.0, 4.0 ] );
// returns [ 1.0, 2.0, 3.0, 4.0 ]
```

The function has the following parameters:

-   **x**: input array.
-   **options**: function options.

The function accepts the following options:

-   **dtype**: output array data type.

To specify the output array data type, set the `dtype` option.

```javascript
var v = abs( [ -1.0, 2.0, -3.0, 4.0 ], {
    'dtype': 'float64'
});
// returns <Float64Array>[ 1.0, 2.0, 3.0, 4.0 ]
```

#### abs.assign( x, out )

Computes the [absolute value][@stdlib/math/base/special/abs] for each element in an input array and assigns results to a provided output array.

```javascript
var zeros = require( '@stdlib/array-zeros' );

var out = zeros( 4, 'float64' );
// returns <Float64Array>[ 0.0, 0.0, 0.0, 0.0 ]

var v = abs.assign( [ -1.0, 2.0, -3.0, 4.0 ], out );
// returns <Float64Array>[ 1.0, 2.0, 3.0, 4.0 ]

var bool = ( v === out );
// returns true
```

The method has the following parameters:

-   **x**: input array.
-   **out**: output array.

## Examples

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

```javascript
var uniform = require( '@stdlib/random-array-uniform' );
var logEach = require( '@stdlib/console-log-each' );
var abs = require( '@stdlib/math-array-special-abs' );

// Generate an array of random numbers:
var x = uniform( 10, -1.0, 1.0, {
    'dtype': 'generic'
});

// Perform element-wise computation:
var y = abs( x );

// Print the results:
logEach( 'abs(%f) = %f', x, y );
