    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>

# FLOAT16_ABS_MASK

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

> Mask for excluding the sign bit of a [half-precision floating-point number][ieee754].

<section class="installation">

## Installation

```bash
npm install @stdlib/constants-float16-abs-mask
```

</section>

<section class="usage">

## Usage

```javascript
var FLOAT16_ABS_MASK = require( '@stdlib/constants-float16-abs-mask' );
```

#### FLOAT16_ABS_MASK

Mask for excluding the sign bit of a [half-precision floating-point number][ieee754].

```javascript
// 0x7fff = 32767 => 0 11111 1111111111
var bool = ( FLOAT16_ABS_MASK === 0x7fff );
// returns true
```

## Examples

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

```javascript
var toWord = require( '@stdlib/number-float16-base-to-word' );
var fromWord = require( '@stdlib/number-float16-base-from-word' );
var toBinaryString = require( '@stdlib/number-uint32-base-to-binary-string' );
var FLOAT16_ABS_MASK = require( '@stdlib/constants-float16-abs-mask' );

var x = -11.5;
var w = toWord( x ); // 1 10010 0111000000
// returns 51648

// Turn off the sign bit and leave other bits unchanged:
var out = w & FLOAT16_ABS_MASK; // 0 10010 0111000000
// returns 18880

// Generate a new value:
out = fromWord( out );
// returns 11.5
