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[] = {

};
