+# srange
+
+> Compute the [range][range] of a one-dimensional single-precision floating-point ndarray.
+
+<section class="intro">
+
+The [**range**][range] is defined as the difference between the maximum and minimum values.
+
+</section>

+<section class="usage">
+
+## Usage
+
+```javascript
+var srange = require( '@stdlib/stats/base/ndarray/srange' );
+```
+
+#### srange( arrays )
+
+Computes the [range][range] of a one-dimensional single-precision floating-point ndarray.
+
+```javascript
+var ndarray = require( '@stdlib/ndarray/base/ctor' );
+
+var xbuf = [ 1.0, 3.0, 4.0, 2.0 ];
+var x = new ndarray( 'float32', xbuf, [ 4 ], [ 1 ], 0, 'row-major' );
+
+var v = srange( [ x ] );
+// returns 3.0
+```
+
+The function has the following parameters:
+
+-   **arrays**: array-like object containing a one-dimensional input ndarray.
+
+</section>
+
+<!-- /.usage -->
+
+<section class="notes">
+
+## Notes
+
+-   If provided an empty one-dimensional ndarray, the function returns `NaN`.
+
+</section>

+<!-- /.notes -->

+<section class="examples">
+
+## Examples
+
+<!-- eslint no-undef: "error" -->
+
+```javascript
+var discreteUniform = require( '@stdlib/random/array/discrete-uniform' );
+var ndarray = require( '@stdlib/ndarray/base/ctor' );
