# ceilf

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

## Installation

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

## Usage

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

#### ceilf( x )

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

```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```

## Examples

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

var x;
var i;

for ( i = 0; i < 100; i++ ) {
x = (randu()*100.0) - 50.0;
console.log( 'ceilf(%d) = %d', x, ceilf( x ) );
}```

## C APIs

### Usage

`#include "stdlib/math/base/special/ceilf.h"`

#### stdlib_base_ceilf( x )

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

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

The function accepts the following arguments:

• x: `[in] float` input value.
`float stdlib_base_ceilf( const float x );`

### Examples

```#include "stdlib/math/base/special/ceilf.h"
#include <stdio.h>

int main() {
float x[] = { 3.14f, -3.14f, 0.0f, 0.0f/0.0f };

float y;
int i;
for ( i = 0; i < 4; i++ ) {
y = stdlib_base_ceilf( x[ i ] );
printf( "ceilf(%f) = %f\n", x[ i ], y );
}
}```

## Notice

This package is part of stdlib, a standard library for JavaScript and Node.js, with an emphasis on numerical and scientific computing. The library provides a collection of robust, high performance libraries for mathematics, statistics, streams, utilities, and more.
