    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

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

#### stdlib_base_complex64_is_equal( z1, z2 )

Tests whether single-precision complex floating-point numbers are equal.

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

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

bool v = stdlib_base_complex64_is_equal( 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_equal( const stdlib_complex64_t z1, const stdlib_complex64_t z2 );
```
