@stdlib/constants-complex128-nan NPM

NAN

Canonical double-precision complex floating-point NaN.

Installation

npm install @stdlib/constants-complex128-nan

Usage

var COMPLEX128_NAN = require( '@stdlib/constants-complex128-nan' );

COMPLEX128_NAN

Canonical double-precision complex floating-point NaN.

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

var re = real( COMPLEX128_NAN );
// returns NaN

var im = imag( COMPLEX128_NAN );
// returns NaN

Examples

var real = require( '@stdlib/complex-real' );
var imag = require( '@stdlib/complex-imag' );
var Complex128Array = require( '@stdlib/array-complex128' );
var COMPLEX128_NAN = require( '@stdlib/constants-complex128-nan' );

var x = new Complex128Array( [ 1.0, 2.0, 3.0, 4.0 ] );
// returns <Complex128Array>

var v = x.get( 0 );
// returns <Complex128>

var re = real( v );
// returns 1.0

var im = imag( v );
// returns 2.0

x.fill( COMPLEX128_NAN );

v = x.get( 0 );
// returns <Complex128>

re = real( v );
// returns NaN

im = imag( v );
// returns NaN

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.
