@stdlib/assert-is-same-float64array NPM

isSameFloat64Array

Test if two arguments are both Float64Arrays and have the same values.

Installation

npm install @stdlib/assert-is-same-float64array

Usage

var isSameFloat64Array = require( '@stdlib/assert-is-same-float64array' );

isSameFloat64Array( v1, v2 )

Tests if two arguments are both Float64Arrays and have the same values.

var Float64Array = require( '@stdlib/array-float64' );

var x = new Float64Array( [ 1.0, 2.0 ] );
var y = new Float64Array( [ 1.0, 2.0 ] );
var bool = isSameFloat64Array( x, y );
// returns true

bool = isSameFloat64Array( x, [ 1.0, 2.0 ] );
// returns false

Notes

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

Examples

var Float64Array = require( '@stdlib/array-float64' );
var isSameFloat64Array = require( '@stdlib/assert-is-same-float64array' );

var x = new Float64Array( [ 1.0, 2.0, 3.0 ] );
var y = new Float64Array( [ 1.0, 2.0, 3.0 ] );
var out = isSameFloat64Array( x, y );
// returns true

x = new Float64Array( [ -0.0, 0.0, -0.0 ] );
y = new Float64Array( [ 0.0, -0.0, 0.0 ] );
out = isSameFloat64Array( x, y );
// returns false

x = new Float64Array( [ NaN, NaN, NaN ] );
y = new Float64Array( [ NaN, NaN, NaN ] );
out = isSameFloat64Array( x, y );
// returns true

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.
