    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>

# isSameFloat64Array

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

> Test if two arguments are both [Float64Arrays][@stdlib/array/float64] and have the [same values][@stdlib/assert/is-same-value].

<section class="installation">

## Installation

```bash
npm install @stdlib/assert-is-same-float64array
```

</section>

<section class="usage">

## Usage

```javascript
var isSameFloat64Array = require( '@stdlib/assert-is-same-float64array' );
```

#### isSameFloat64Array( v1, v2 )

Tests if two arguments are both [Float64Arrays][@stdlib/array/float64] and have the [same values][@stdlib/assert/is-same-value].

```javascript
var Float64Array = require( '@stdlib/array-float64' );

var x = new Float64Array( [ 1.0, 2.0 ] );
var y = new Float64Array( [ 1.0, 2.0 ] );
var bool = isSameFloat64Array( x, y );
// returns true

bool = isSameFloat64Array( x, [ 1.0, 2.0 ] );
// returns false
```

</section>

<!-- /.usage -->

<section class="notes">

## Notes

-   In contrast to the strict equality operator `===`, the function distinguishes between `+0` and `-0` and treats `NaNs` as the [same value][@stdlib/assert/is-same-value].

</section>

<!-- /.notes -->

<section class="examples">

## Examples

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

```javascript
var Float64Array = require( '@stdlib/array-float64' );
var isSameFloat64Array = require( '@stdlib/assert-is-same-float64array' );

var x = new Float64Array( [ 1.0, 2.0, 3.0 ] );
var y = new Float64Array( [ 1.0, 2.0, 3.0 ] );
var out = isSameFloat64Array( x, y );
// returns true

x = new Float64Array( [ -0.0, 0.0, -0.0 ] );
y = new Float64Array( [ 0.0, -0.0, 0.0 ] );
out = isSameFloat64Array( x, y );
// returns false

x = new Float64Array( [ NaN, NaN, NaN ] );
y = new Float64Array( [ NaN, NaN, NaN ] );
out = isSameFloat64Array( x, y );
// returns true
```
