    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>

<section class="installation">

## Installation

```bash
npm install @stdlib/math-base-special-cceilf
```

</section>

<section class="usage">

## Usage

```javascript
var cceilf = require( '@stdlib/math-base-special-cceilf' );
```

#### cceilf( z )

Rounds a single-precision complex floating-point number toward positive infinity.

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

var v = cceilf( new Complex64( -1.5, 2.5 ) );
// returns <Complex64>

var re = real( v );
// returns -1.0

var im = imag( v );
// returns 3.0
```

## Examples

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

```javascript
var uniform = require( '@stdlib/random-base-uniform' ).factory;
var Complex64 = require( '@stdlib/complex-float32-ctor' );
var cceilf = require( '@stdlib/math-base-special-cceilf' );

var rand = uniform( -50.0, 50.0 );

var z;
var i;
for ( i = 0; i < 100; i++ ) {
    z = new Complex64( rand(), rand() );
    console.log( 'cceilf(%s) = %s', z, cceilf( z ) );

### Usage

```c
#include "stdlib/math/base/special/cceilf.h"
```

#### stdlib_base_cceilf( z )

Rounds a single-precision complex floating-point number toward positive infinity.

```c
#include <complex.h>

float complex y = stdlib_base_cceilf( 2.5f-1.5f*I );
// returns 3.0f-1.0f*I
```

The function accepts the following arguments:

-   **z**: `[in] float complex` input value.

```c
float complex stdlib_base_cceilf( const float complex z );
```
