    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>

npm install @stdlib/math-base-special-ceilf
```

</section>

<section class="usage">

## Usage

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

#### ceilf( x )

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

```javascript
var v = ceilf( -4.2 );
// returns -4.0

v = ceilf( 9.99999 );
// returns 10.0

v = ceilf( 0.0 );
// returns 0.0

v = ceilf( NaN );
// returns NaN
```

var uniform = require( '@stdlib/random-array-uniform' );
var logEachMap = require( '@stdlib/console-log-each-map' );
var ceilf = require( '@stdlib/math-base-special-ceilf' );

var opts = {
    'dtype': 'float32'
};
var x = uniform( 100, -50.0, 50.0, opts );

#### stdlib_base_ceilf( x )

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

```c
float y = stdlib_base_ceilf( 3.14f );
// returns 4.0f
```

The function accepts the following arguments:

-   **x**: `[in] float` input value.
