cceilf

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

Installation

npm install @stdlib/math-base-special-cceilf

Usage

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

cceilf( z )

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

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

Examples

var uniform = require( '@stdlib/random-base-uniform' ).factory;
var Complex64 = require( '@stdlib/complex-float32-ctor' );
var cceilf = require( '@stdlib/math-base-special-cceilf' );

var rand = uniform( -50.0, 50.0 );

var z;
var i;
for ( i = 0; i < 100; i++ ) {
    z = new Complex64( rand(), rand() );
    console.log( 'cceilf(%s) = %s', z, cceilf( z ) );
}

C APIs

Usage

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

stdlib_base_cceilf( z )

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

#include <complex.h>

float complex y = stdlib_base_cceilf( 2.5f-1.5f*I );
// returns 3.0f-1.0f*I

The function accepts the following arguments:

• z: [in] float complex input value.

float complex stdlib_base_cceilf( const float complex z );

Examples

#include "stdlib/math/base/special/cceilf.h"
#include <stdio.h>
#include <complex.h>

int main( void ) {
    const float complex x[] = { 3.14f+1.5f*I, -3.14f-1.5f*I, 0.0f+0.0f*I, 0.0f/0.0f+0.0f/0.0f*I };

    float complex v;
    float complex y;
    int i;
    for ( i = 0; i < 4; i++ ) {
        v = x[ i ];
        y = stdlib_base_cceilf( v );
        printf( "cceilf(%f + %fi) = %f + %fi\n", crealf( v ), cimagf( v ), crealf( y ), cimagf( y ) );
    }
}
