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!

Complex Numbers

Create a complex number.

Installation

npm install @stdlib/complex-cmplx

Usage

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

complex( real, imag[, dtype] )

Creates a complex number, where real and imag are the real and imaginary components, respectively.

var z = complex( 5.0, 3.0 );
// returns <Complex128>

By default, the function returns a 128-bit complex number. To specify an alternative underlying data type, set the dtype parameter to one of the following:

• 'float64': store real and imaginary components as double-precision floating-point numbers.
• 'float32': store real and imaginary components as single-precision floating-point numbers.

var z = complex( 5.0, 3.0, 'float32' );
// returns <Complex64>

Examples

var discreteUniform = require( '@stdlib/random-base-discrete-uniform' ).factory;
var complex = require( '@stdlib/complex-cmplx' );

var rand = discreteUniform( -50, 50 );

var z;
var i;
for ( i = 0; i < 100; i++ ) {
    z = complex( rand(), rand(), 'float64' );
    console.log( z.toString() );
}
