Package Exports
- @stdlib/math-base-special-cceil
- @stdlib/math-base-special-cceil/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-cceil) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.
Readme
cceil
Round a double-precision complex floating-point number toward positive infinity.
Installation
npm install @stdlib/math-base-special-cceilUsage
var cceil = require( '@stdlib/math-base-special-cceil' );cceil( z )
Rounds a double-precision complex floating-point number toward positive infinity.
var Complex128 = require( '@stdlib/complex-float64' );
var real = require( '@stdlib/complex-real' );
var imag = require( '@stdlib/complex-imag' );
var v = cceil( new Complex128( -1.5, 2.5 ) );
// returns <Complex128>
var re = real( v );
// returns -1.0
var im = imag( v );
// returns 3.0Examples
var uniform = require( '@stdlib/random-base-uniform' ).factory;
var Complex128 = require( '@stdlib/complex-float64' );
var cceil = require( '@stdlib/math-base-special-cceil' );
var rand = uniform( -50.0, 50.0 );

Usage
#include "stdlib/math/base/special/cceil.h"stdlib_base_cceil( z )
Rounds a double-precision complex floating-point number toward positive infinity.
#include <complex.h>
double complex y = stdlib_base_cceil( 2.5-1.5*I );
// returns 3.0-1.0*IThe function accepts the following arguments:
- z:
[in] double complexinput value.

double complex y;
int i;
for ( i = 0; i < 4; i++ ) {
