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 , and please consider financially supporting stdlib. We greatly appreciate your continued support!
128-bit complex number.
import Complex128 from 'https://cdn.jsdelivr.net/gh/stdlib-js/complex-float64-ctor@esm/index.mjs';128-bit complex number constructor, where real and imag are the real and imaginary components, respectively.
var z = new Complex128( 5.0, 3.0 );
// returns <Complex128>Size (in bytes) of each component.
var nbytes = Complex128.BYTES_PER_ELEMENT;
// returns 8Size (in bytes) of each component.
var z = new Complex128( 5.0, 3.0 );
var nbytes = z.BYTES_PER_ELEMENT;
// returns 8Length (in bytes) of a complex number.
var z = new Complex128( 5.0, 3.0 );
var nbytes = z.byteLength;
// returns 16A Complex128 instance has the following properties...
A read-only property returning the real component.
var z = new Complex128( 5.0, 3.0 );
var re = z.re;
// returns 5.0A read-only property returning the imaginary component.
var z = new Complex128( 5.0, -3.0 );
var im = z.im;
// returns -3.0These methods do not mutate a Complex128 instance and, instead, return a complex number representation.
Returns a string representation of a Complex128 instance.
var z = new Complex128( 5.0, 3.0 );
var str = z.toString();
// returns '5 + 3i'
z = new Complex128( -5.0, -3.0 );
str = z.toString();
// returns '-5 - 3i'Returns a JSON representation of a Complex128 instance. JSON.stringify() implicitly calls this method when stringifying a Complex128 instance.
var z = new Complex128( 5.0, -3.0 );
var o = z.toJSON();
/*
{
"type": "Complex128",
"re": 5.0,
"im": -3.0
}
*/To revive a Complex128 number from a JSON string, see @stdlib/complex/float64/reviver.
- Both the real and imaginary components are stored as double-precision floating-point numbers.
