    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>

> Test if two numbers are [coprime][coprime-integers].

<section class="intro">

Two integers `a` and `b` are said to be **coprime** (or **relatively prime** or **mutually prime**) if the only positive integer that divides both of them is `1`.

</section>

<!-- /.intro -->

<section class="installation">

## Installation

```bash
npm install @stdlib/math-base-assert-is-coprime
```

</section>

<section class="usage">

## Usage

```javascript
var isCoprime = require( '@stdlib/math-base-assert-is-coprime' );
```

#### isCoprime( a, b )

Tests if two numbers are [coprime][coprime-integers].

```javascript
var bool = isCoprime( 14.0, 15.0 );
// returns true

bool = isCoprime( 14.0, 21.0 );
// returns false
```

## Examples

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

```javascript
var isCoprime = require( '@stdlib/math-base-assert-is-coprime' );

var bool = isCoprime( 5.0, 7.0 );
// returns true

bool = isCoprime( 5.0, 15.0 );
// returns false

bool = isCoprime( NaN, NaN );
// returns false
