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!

isSameValue

Test whether two double-precision complex floating-point numbers are the same value.

Usage

import isSameValue from 'https://cdn.jsdelivr.net/gh/stdlib-js/complex-base-assert-is-same-value@deno/mod.js';

isSameValue( z1, z2 )

Tests whether two double-precision complex floating-point numbers are the same value.

import Complex128 from 'https://cdn.jsdelivr.net/gh/stdlib-js/complex-float64@deno/mod.js';

var z1 = new Complex128( 5.0, 3.0 );
var z2 = new Complex128( 5.0, 3.0 );

var out = isSameValue( z1, z2 );
// returns true

In contrast to the strict equality operator ===, the function distinguishes between +0 and -0 and treats NaNs as the same value.

import Complex128 from 'https://cdn.jsdelivr.net/gh/stdlib-js/complex-float64@deno/mod.js';

var z1 = new Complex128( NaN, NaN );
var z2 = new Complex128( NaN, NaN );

var out = isSameValue( z1, z2 );
// returns true

z1 = new Complex128( -0.0, 0.0 );
z2 = new Complex128( 0.0, -0.0 );

out = isSameValue( z1, z2 );
// returns false

Notes

• The function implements the SameValue Algorithm as specified in ECMAScript 5.

Examples

import Complex128 from 'https://cdn.jsdelivr.net/gh/stdlib-js/complex-float64@deno/mod.js';
import isSameValue from 'https://cdn.jsdelivr.net/gh/stdlib-js/complex-base-assert-is-same-value@deno/mod.js';

var z1 = new Complex128( 5.0, 3.0 );
var z2 = new Complex128( 5.0, 3.0 );
var out = isSameValue( z1, z2 );
// returns true

z1 = new Complex128( -5.0, -3.0 );
z2 = new Complex128( 5.0, 3.0 );
out = isSameValue( z1, z2 );
// returns false

z1 = new Complex128( NaN, 3.0 );
z2 = new Complex128( NaN, 3.0 );
out = isSameValue( z1, z2 );
// returns true
