    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 each component of 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
```

var rand = uniform( -50.0, 50.0 );

### Usage

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

#### stdlib_base_cceilf( z )

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

```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( 2.5f, -1.5f );

stdlib_complex64_t out = stdlib_base_cceilf( z );

float re = stdlib_complex64_real( out );
// returns 3.0f

float im = stdlib_complex64_imag( out );
// returns -1.0f
```

The function accepts the following arguments:

-   **z**: `[in] stdlib_complex64_t` input value.

```c
stdlib_complex64_t stdlib_base_cceilf( const stdlib_complex64_t z );
```
