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!

isNotEqualf

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

Installation

npm install @stdlib/complex-float32-base-assert-is-not-equal

Usage

var isNotEqualf = require( '@stdlib/complex-float32-base-assert-is-not-equal' );

isNotEqualf( z1, z2 )

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

var Complex64 = require( '@stdlib/complex-float32-ctor' );

var z1 = new Complex64( 5.0, 3.0 );
var z2 = new Complex64( 5.0, -3.0 );

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

Examples

var Complex64 = require( '@stdlib/complex-float32-ctor' );
var isNotEqualf = require( '@stdlib/complex-float32-base-assert-is-not-equal' );

var z1 = new Complex64( 5.0, 3.0 );
var z2 = new Complex64( 5.0, 3.0 );
var out = isNotEqualf( z1, z2 );
// returns false

z1 = new Complex64( -5.0, -3.0 );
z2 = new Complex64( 5.0, 3.0 );
out = isNotEqualf( z1, z2 );
// returns true

z1 = new Complex64( NaN, 3.0 );
z2 = new Complex64( NaN, 3.0 );
out = isNotEqualf( z1, z2 );
// returns true

C APIs

Usage

#include "stdlib/complex/float32/base/assert/is_not_equal.h"

stdlib_base_complex64_is_not_equal( z1, z2 )

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

#include "stdlib/complex/float32/ctor.h"
#include <stdbool.h>

stdlib_complex64_t z1 = stdlib_complex64( 5.0, 2.0 );
stdlib_complex64_t z2 = stdlib_complex64( 5.0, -2.0 );

bool v = stdlib_base_complex64_is_not_equal( z1, z2 );

The function accepts the following arguments:

• z1: [in] stdlib_complex64_t first single-precision complex floating-point number.
• z2: [in] stdlib_complex64_t second single-precision complex floating-point number.

bool stdlib_base_complex64_is_not_equal( const stdlib_complex64_t z1, const stdlib_complex64_t z2 );

Examples

#include "stdlib/complex/float32/base/assert/is_not_equal.h"
#include "stdlib/complex/float32/ctor.h"
#include <stdbool.h>
#include <stdio.h>

int main( void ) {
    const stdlib_complex64_t z[] = {
        stdlib_complex64( 5.0f, 2.0f ),
        stdlib_complex64( -2.0f, 1.0f ),
        stdlib_complex64( 0.0f, -0.0f ),
        stdlib_complex64( 0.0f/0.0f, 0.0f/0.0f )
    };

    bool v;
    int i;
    for ( i = 0; i < 4; i++ ) {
        v = stdlib_base_complex64_is_not_equal( z[ i ], z[ i ] );
        printf( "Equal? %s\n", ( v ) ? "True" : "False" );
    }
}
