    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-base-assert-is-same-valuef
```

</section>

<section class="usage">

## Usage

```javascript
var isSameValuef = require( '@stdlib/complex-base-assert-is-same-valuef' );
```

#### isSameValuef( z1, z2 )

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

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

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

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

In contrast to the strict equality operator `===`, the function distinguishes between `+0` and `-0` and treats `NaNs` as the same value.

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

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

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

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

out = isSameValuef( z1, z2 );
// returns false
```

## Notes

-   The function implements the [SameValue Algorithm][ecma-262-same-value-algorithm] as specified in ECMAScript 5.

out = isSameValuef( z1, z2 );

z2 = new Complex64( NaN, 3.0 );

### Usage

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

#### stdlib_base_complex64_is_same_value( z1, z2 )

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

```c
#include "stdlib/complex/float32.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( 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( const stdlib_complex64_t z1, const stdlib_complex64_t z2 );
```
