Test if two arguments are both Float64Arrays and contain respective elements which are approximately equal within a specified number of ULPs (units in the last place).
npm install @stdlib/assert-is-almost-equal-float64arrayWe 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!

Tests if two arguments are both [Float64Arrays][@stdlib/array/float64] and contain respective elements which are [approximately equal][@stdlib/assert/is-almost-equal] within a specified number of ULPs (units in the last place).
`javascript
var EPS = require( '@stdlib/constants-float64-eps' );
var Float64Array = require( '@stdlib/array-float64' );
var x = new Float64Array( [ 1.0, 2.0 ] );
var y = new Float64Array( [ 1.0+EPS, 2.0 ] );
var bool = isAlmostEqualFloat64Array( x, y, 0 );
// returns false
bool = isAlmostEqualFloat64Array( x, y, 1 );
// returns true
bool = isAlmostEqualFloat64Array( x, [ 1.0, 2.0 ], 1 );
// returns false
`
- The function returns false if either input value is a Float64Array containing NaN.-0
- The function does not distinguish between and +0, treating them as equal.
`javascript
var Float64Array = require( '@stdlib/array-float64' );
var isAlmostEqualFloat64Array = require( '@stdlib/assert-is-almost-equal-float64array' );
var x = new Float64Array( [ 1.0, 2.0, 3.0 ] );
var y = new Float64Array( [ 1.0, 2.0, 3.0 ] );
var out = isAlmostEqualFloat64Array( x, y, 0 );
// returns true
x = new Float64Array( [ -0.0, 0.0, -0.0 ] );
y = new Float64Array( [ 0.0, -0.0, 0.0 ] );
out = isAlmostEqualFloat64Array( x, y, 1 );
// returns true
x = new Float64Array( [ NaN, NaN, NaN ] );
y = new Float64Array( [ NaN, NaN, NaN ] );
out = isAlmostEqualFloat64Array( x, y, 0 );
// returns false
