    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>

## Installation

```bash
npm install @stdlib/complex-float32-base-assert-is-same-value-zero
```

</section>

<section class="usage">

## Usage

```javascript
var isSameValueZero = require( '@stdlib/complex-float32-base-assert-is-same-value-zero' );
```

#### isSameValueZero( z1, z2 )

Tests whether two single-precision complex floating-point numbers are the same value.

```javascript
var Complex64 = require( '@stdlib/complex-float32-ctor' );

var z1 = new Complex64( 5.0, 3.0 );
var z2 = new Complex64( 5.0, 3.0 );

var out = isSameValueZero( z1, z2 );
// returns true
```

In contrast to the strict equality operator `===`, the function treats `NaNs` as the same value.

```javascript
var Complex64 = require( '@stdlib/complex-float32-ctor' );

var z1 = new Complex64( NaN, NaN );
var z2 = new Complex64( NaN, NaN );

var out = isSameValueZero( z1, z2 );
// returns true
```

In contrast to the [SameValue Algorithm][@stdlib/complex/float32/base/assert/is-same-value] (as specified in ECMAScript 5), the function does not distinguish between `+0` and `-0`.

```javascript
var Complex64 = require( '@stdlib/complex-float32-ctor' );

var z1 = new Complex64( -0.0, 0.0 );
var z2 = new Complex64( 0.0, -0.0 );

var out = isSameValueZero( z1, z2 );
// returns true
```

var z2 = new Complex64( 5.0, 3.0 );
var out = isSameValueZero( z1, z2 );
// returns true

z1 = new Complex64( -5.0, -3.0 );
z2 = new Complex64( 5.0, 3.0 );
out = isSameValueZero( z1, z2 );
// returns false

z1 = new Complex64( NaN, 3.0 );
z2 = new Complex64( NaN, 3.0 );
out = isSameValueZero( z1, z2 );
// returns true

### Usage

```c
#include "stdlib/complex/float32/base/assert/is_same_value_zero.h"
```

#### stdlib_base_complex64_is_same_value_zero( z1, z2 )

Tests whether two single-precision complex floating-point numbers are the same value.

```c
#include "stdlib/complex/float32/ctor.h"
#include <stdbool.h>

stdlib_complex64_t z1 = stdlib_complex64( 5.0f, 2.0f );
stdlib_complex64_t z2 = stdlib_complex64( 5.0f, 2.0f );

bool v = stdlib_base_complex64_is_same_value_zero( z1, z2 );
```

The function accepts the following arguments:

-   **z1**: `[in] stdlib_complex64_t` first single-precision complex floating-point number.
-   **z2**: `[in] stdlib_complex64_t` second single-precision complex floating-point number.

```c
bool stdlib_base_complex64_is_same_value_zero( const stdlib_complex64_t z1, const stdlib_complex64_t z2 );
```
