    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.
