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!

NPM version Build Status Coverage Status

Return the data type of a complex number.

Installation

npm install @stdlib/complex-dtype

Usage

var dtype = require( '@stdlib/complex-dtype' );
dtype( value )

Returns the data type of a complex number.

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

var dt = dtype( new Complex128( 1.0, 2.0 ) );
// returns 'complex128'

If provided an argument having an unknown or unsupported data type, the function returns null.

var dt = dtype( 'beep' );
// returns null

Examples

var dtypes = require( '@stdlib/complex-dtypes' );
var ctors = require( '@stdlib/complex-ctors' );
var dtype = require( '@stdlib/complex-dtype' );

// Get a list of supported complex number data types:
var DTYPES = dtypes();

// For each supported data type, create a complex number and confirm its data type...
var ctor;
var dt;
var i;
for ( i = 0; i < DTYPES.length; i++ ) {
    ctor = ctors( DTYPES[ i ] );
    dt = dtype( new ctor( 1.0, 2.0 ) );
    console.log( '%s == %s => %s', DTYPES[ i ], dt, DTYPES[ i ] === dt );
}
