    ceilf

    NPM version Build Status Coverage Status

    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 );
        }
    }
