About stdlib...

We believe in a future in which the web is a preferred environment for numerical computation. To help realize this future, we've built stdlib. stdlib is a standard library, with an emphasis on numerical and scientific computation, written in JavaScript (and C) for execution in browsers and in Node.js.

The library is fully decomposable, being architected in such a way that you can swap out and mix and match APIs and functionality to cater to your exact preferences and use cases.

When you use stdlib, you can be absolutely certain that you are using the most thorough, rigorous, well-written, studied, documented, tested, measured, and high-quality code out there.

To join us in bringing numerical computing to the web, get started by checking us out on GitHub, and please consider financially supporting stdlib. We greatly appreciate your continued support!

isComplexLike

Test if a value is a complex number-like object.

Installation

npm install @stdlib/assert-is-complex-like

Alternatively,

• To load the package in a website via a script tag without installation and bundlers, use the ES Module available on the esm branch (see README).
• If you are using Deno, visit the deno branch (see README for usage intructions).
• For use in Observable, or in browser/node environments, use the Universal Module Definition (UMD) build available on the umd branch (see README).

The branches.md file summarizes the available branches and displays a diagram illustrating their relationships.

To view installation and usage instructions specific to each branch build, be sure to explicitly navigate to the respective README files on each branch, as linked to above.

Usage

var isComplexLike = require( '@stdlib/assert-is-complex-like' );

isComplexLike( value )

Tests if a value is a complex number-like object.

var Complex128 = require( '@stdlib/complex-float64-ctor' );
var Complex64 = require( '@stdlib/complex-float32-ctor' );

var x = new Complex128( 1.0, 3.0 );
var bool = isComplexLike( x );
// returns true

x = new Complex64( 3.0, 1.0 );
bool = isComplexLike( x );
// returns true

x = {
    're': 1.0,
    'im': -1.0
};
bool = isComplexLike( x );
// returns true

Notes

• A complex number-like object is defined as an object having the following properties assigned to numeric values:

  • re: real component.
  • im: imaginary component.

Examples

var Complex64 = require( '@stdlib/complex-float32-ctor' );
var Complex128 = require( '@stdlib/complex-float64-ctor' );
var isComplexLike = require( '@stdlib/assert-is-complex-like' );

var out = isComplexLike( new Complex64( 2.0, 2.0 ) );
// returns true

out = isComplexLike( new Complex128( 3.0, 1.0 ) );
// returns true

out = isComplexLike( { 're': 1.0, 'im': -1.0 } );
// returns true

out = isComplexLike( {} );
// returns false

out = isComplexLike( null );
// returns false
