@stdlib/complex-reviver-float64 NPM

reviveComplex128

Revive a JSON-serialized 128-bit complex number.

Installation

npm install @stdlib/complex-reviver-float64

Usage

var reviveComplex128 = require( '@stdlib/complex-reviver-float64' );

reviveComplex128( key, value )

Revives a JSON-serialized 128-bit complex number.

var parseJSON = require( '@stdlib/utils-parse-json' );

var str = '{"type":"Complex128","re":5,"im":3}';

var z = parseJSON( str, reviveComplex128 );
// returns <Complex128>

For details on the JSON serialization format, see Complex128.

Examples

var Complex128 = require( '@stdlib/complex-float64' );
var parseJSON = require( '@stdlib/utils-parse-json' );
var reviveComplex128 = require( '@stdlib/complex-reviver-float64' );

var z = new Complex128( 5.0, 3.0 );
var str = JSON.stringify( z );
// returns '{"type":"Complex128","re":5,"im":3}'

var w = parseJSON( str, reviveComplex128 );
if ( w instanceof Error ) {
    throw w;
}
var bool = ( w instanceof z.constructor );
// returns true

bool = ( w.re === z.re );
// returns true

bool = ( w.im === z.im );
// returns true

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.
