@stdlib/complex-float64-base-assert-is-not-equal

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!

isNotEqual

Test whether two double-precision complex floating-point numbers are not equal.

Installation

npm install @stdlib/complex-float64-base-assert-is-not-equal

Usage

var isNotEqual = require( '@stdlib/complex-float64-base-assert-is-not-equal' );

isNotEqual( z1, z2 )

Tests whether two double-precision complex floating-point numbers are not equal.

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

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

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

Examples

var Complex128 = require( '@stdlib/complex-float64-ctor' );
var isNotEqual = require( '@stdlib/complex-float64-base-assert-is-not-equal' );

var z1 = new Complex128( 5.0, 3.0 );
var z2 = new Complex128( 5.0, 3.0 );
var out = isNotEqual( z1, z2 );
// returns false

z1 = new Complex128( -5.0, -3.0 );
z2 = new Complex128( 5.0, 3.0 );
out = isNotEqual( z1, z2 );
// returns true

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

C APIs

Usage

#include "stdlib/complex/float64/base/assert/is_not_equal.h"

stdlib_base_complex128_is_not_equal( z1, z2 )

Tests whether double-precision complex floating-point numbers are not equal.

#include "stdlib/complex/float64/ctor.h"
#include <stdbool.h>

stdlib_complex128_t z1 = stdlib_complex128( 5.0, 2.0 );
stdlib_complex128_t z2 = stdlib_complex128( 5.0, -2.0 );

bool v = stdlib_base_complex128_is_not_equal( z1, z2 );

The function accepts the following arguments:

• z1: [in] stdlib_complex128_t first double-precision complex floating-point number.
• z2: [in] stdlib_complex128_t second double-precision complex floating-point number.

bool stdlib_base_complex128_is_not_equal( const stdlib_complex128_t z1, const stdlib_complex128_t z2 );

Examples

#include "stdlib/complex/float64/base/assert/is_not_equal.h"
#include "stdlib/complex/float64/ctor.h"
#include <stdbool.h>
#include <stdio.h>

int main( void ) {
    const stdlib_complex128_t z[] = {
        stdlib_complex128( 5.0, 2.0 ),
        stdlib_complex128( -2.0, 1.0 ),
        stdlib_complex128( 0.0, -0.0 ),
        stdlib_complex128( 0.0/0.0, 0.0/0.0 )
    };

    bool v;
    int i;
    for ( i = 0; i < 4; i++ ) {
        v = stdlib_base_complex128_is_not_equal( z[ i ], z[ i ] );
        printf( "Equal? %s\n", ( v ) ? "True" : "False" );
    }
}

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.
