Package Exports

@stdlib/complex-real

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/complex-real) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

real

Return the real component of a complex number.

Installation

npm install @stdlib/complex-real

Usage

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

real( z )

Returns the real component of a complex number.

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

var z = new Complex128( 5.0, 3.0 );
var re = real( z );
// returns 5.0

Examples

var Complex128 = require( '@stdlib/complex-float64' );
var randu = require( '@stdlib/random-base-randu' );
var round = require( '@stdlib/math-base-special-round' );
var real = require( '@stdlib/complex-real' );

var re;
var im;
var z;
var i;

for ( i = 0; i < 100; i++ ) {
    re = round( (randu()*100.0) - 50.0 );
    im = round( (randu()*50.0) - 25.0 );
    z = new Complex128( re, im );
    console.log( 'real(%s) = %d', z.toString(), real( z ) );
}
