isSameComplex128

Test if two arguments are both double-precision complex floating-point numbers and have the same value.

Usage

var isSameComplex128 = require( '@stdlib/assert/is-same-complex128' );

isSameComplex128( v1, v2 )

Tests if two arguments are both double-precision complex floating-point numbers and have the same value.

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

var x = new Complex128( 1.0, 2.0 );
var y = new Complex128( 1.0, 2.0 );
var bool = isSameComplex128( x, y );
// returns true

Notes

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

Examples

var Complex128 = require( '@stdlib/complex/float64/ctor' );
var isSameComplex128 = require( '@stdlib/assert/is-same-complex128' );

var x = new Complex128( 1.0, 2.0 );
var y = new Complex128( 1.0, 2.0 );
var out = isSameComplex128( x, y );
// returns true

x = new Complex128( 0.0, -0.0 );
y = new Complex128( -0.0, 0.0 );
out = isSameComplex128( x, y );
// returns false

x = new Complex128( NaN, NaN );
y = new Complex128( NaN, NaN );
out = isSameComplex128( x, y );
// returns true
