## Usage
38+
39+
```javascript
40+
var hasAlmostSameValues = require( '@stdlib/array/base/assert/has-almost-same-values' );
41+
```
42+
43+
#### hasAlmostSameValues( x, y, maxULP )
44+
45+
Tests if two arrays have respective elements which are approximately the same value within a specified number of ULPs (units in the last place).
46+
47+
```javascript
48+
var x = [ 0, 0, 1, 0 ];
49+
var y = [ 0, 0, 1, 0 ];
50+
51+
var bool = hasAlmostSameValues( x, y, 1 );
52+
// returns true
53+
```
54+
55+
</section>

<!-- Package usage notes. Make sure to keep an empty line after the `section` element and another before the `/section` close. -->
60+
61+
<section class="notes">
62+
63+
## Notes
64+
65+
- In contrast to the strict equality operator `===`, the function distinguishes between `+0` and `-0` and treats `NaNs` as the same value.
66+
- If provided arrays of unequal length, the function returns `false`.
67+
- The function does **not** skip `undefined` elements and is thus not optimized for sparse arrays.
