# ceilf

> Round a single-precision floating-point number toward positive infinity.

<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
```
