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

Package Exports

  • @stdlib/math-base-special-cceilf
  • @stdlib/math-base-special-cceilf/lib/index.js

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (@stdlib/math-base-special-cceilf) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

cceilf

NPM version Build Status Coverage Status

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' );
var real = require( '@stdlib/complex-real' );
var imag = require( '@stdlib/complex-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' );
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() {
    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 ) );
    }
}

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.
