# srange
22+
23+
> Compute the [range][range] of a one-dimensional single-precision floating-point ndarray.
24+
25+
<section class="intro">
26+
27+
The [**range**][range] is defined as the difference between the maximum and minimum values.
28+
29+
</section>
30+
31+
<!-- /.intro -->
32+
33+
<section class="usage">
34+
35+
## Usage
36+
37+
```javascript
38+
var srange = require( '@stdlib/stats/base/ndarray/srange' );
39+
```
40+
41+
#### srange( arrays )
42+
43+
Computes the [range][range] of a one-dimensional single-precision floating-point ndarray.
44+
45+
```javascript
46+
var ndarray = require( '@stdlib/ndarray/base/ctor' );
47+
48+
var xbuf = [ 1.0, 3.0, 4.0, 2.0 ];
49+
var x = new ndarray( 'float32', xbuf, [ 4 ], [ 1 ], 0, 'row-major' );
50+
51+
var v = srange( [ x ] );
52+
// returns 3.0
53+
```
54+
55+
The function has the following parameters:
56+
57+
- **arrays**: array-like object containing a one-dimensional input ndarray.
58+
59+
</section>
60+
61+
<!-- /.usage -->
62+
63+
<section class="notes">
64+
65+
## Notes
66+
67+
- If provided an empty one-dimensional ndarray, the function returns `NaN`.
