    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 sub = require( '@stdlib/number-float16-base-sub' );
```

#### sub( x, y )

Subtracts two half-precision floating-point numbers.

```javascript
var v = sub( -1.0, 5.0 );
// returns -6.0

v = sub( 2.0, 5.0 );
// returns -3.0

v = sub( 0.0, 5.0 );
// returns -5.0

v = sub( -0.0, 0.0 );
// returns -0.0

v = sub( NaN, NaN );
// returns NaN
```
