    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>

> Add two single-precision complex floating-point numbers.

<section class="intro">

</section>

<!-- /.intro -->

<section class="installation">

## Installation

```bash
npm install @stdlib/complex-float32-base-add
```

</section>

<section class="usage">

## Usage

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

#### add( z1, z2 )

Adds two single-precision complex floating-point numbers.

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

var z = new Complex64( -1.5, 2.5 );

var v = add( z, z );
// returns <Complex64>[ -3.0, 5.0 ]
```

#### add.assign( re1, im1, re2, im2, out, strideOut, offsetOut )

Adds two single-precision complex floating-point numbers and assigns results to a provided output array.

```javascript
var Float32Array = require( '@stdlib/array-float32' );

var out = new Float32Array( 2 );
var v = add.assign( 5.0, 3.0, -2.0, 1.0, out, 1, 0 );
// returns <Float32Array>[ 3.0, 4.0 ]

var bool = ( out === v );
// returns true
```

The function supports the following parameters:

-   **re1**: real component of the first complex number.
-   **im1**: imaginary component of the first complex number.
-   **re2**: real component of the second complex number.
-   **im2**: imaginary component of the second complex number.
-   **out**: output array.
-   **strideOut**: stride length for `out`.
-   **offsetOut**: starting index for `out`.

#### add.strided( z1, sz1, oz1, z2, sz2, oz2, out, so, oo )

Adds two single-precision complex floating-point numbers stored in real-valued strided array views and assigns results to a provided strided output array.

```javascript
var Float32Array = require( '@stdlib/array-float32' );

var z1 = new Float32Array( [ 5.0, 3.0 ] );
var z2 = new Float32Array( [ -2.0, 1.0 ] );
var out = new Float32Array( 2 );

var v = add.strided( z1, 1, 0, z2, 1, 0, out, 1, 0 );
// returns <Float32Array>[ 3.0, 4.0 ]

var bool = ( out === v );
// returns true
```

The function supports the following parameters:

-   **z1**: first complex number strided array view.
-   **sz1**: stride length for `z1`.
-   **oz1**: starting index for `z1`.
-   **z2**: second complex number strided array view.
-   **sz2**: stride length for `z2`.
-   **oz2**: starting index for `z2`.
-   **out**: output array.
-   **so**: stride length for `out`.
-   **oo**: starting index for `out`.

## Examples

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

```javascript
var Complex64Array = require( '@stdlib/array-complex64' );
var discreteUniform = require( '@stdlib/random-array-discrete-uniform' );
var logEachMap = require( '@stdlib/console-log-each-map' );
var add = require( '@stdlib/complex-float32-base-add' );

// Generate arrays of random values:
var z1 = new Complex64Array( discreteUniform( 200, -50, 50 ) );
var z2 = new Complex64Array( discreteUniform( 200, -50, 50 ) );

// Perform element-wise addition:
logEachMap( '(%s) + (%s) = %s', z1, z2, add );

### Usage

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

#### stdlib_base_complex64_add( z1, z2 )

Adds two single-precision complex floating-point numbers.

```c
#include "stdlib/complex/float32/ctor.h"
#include "stdlib/complex/float32/real.h"
#include "stdlib/complex/float32/imag.h"

stdlib_complex64_t z = stdlib_complex64( 3.0f, -2.0f );

stdlib_complex64_t out = stdlib_base_complex64_add( z, z );

float re = stdlib_complex64_real( out );
// returns 6.0f

float im = stdlib_complex64_imag( out );
// returns -4.0f
```

The function accepts the following arguments:

-   **z1**: `[in] stdlib_complex64_t` input value.
-   **z2**: `[in] stdlib_complex64_t` input value.

```c
stdlib_complex64_t stdlib_base_complex64_add( const stdlib_complex64_t z1, const stdlib_complex64_t z2 );
```
