+## Usage
+
+```javascript
+var minmaxabsf = require( '@stdlib/math/base/special/minmaxabsf' );
+```
+
+#### minmaxabsf( x,y )
+
+Returns the minimum and maximum absolute single-precision floating-point values in a single pass.
+
+```javascript
+var v = minmaxabsf( 4.0, 3.0 );
+// returns <Float32Array>[ 3.0, 4.0 ]
+
+v = minmaxabsf( +0.0, -0.0 );
+// returns <Float32Array>[ 0.0, 0.0 ]
+```
+
+If any argument is `NaN`, the function returns `Nan` for both the minimum value and the maximum value.
+
+```javascript
+var v = minmaxabsf( 4.2, NaN );
+// returns <Float32Array>[ NaN, NaN ]
+
+v = minmaxabsf( NaN, 3.14 );
+// returns <Float32Array>[ NaN, NaN ]
+```
+
+#### minmaxabsf.assign( x, y, out, stride, offset )
+
+Returns the minimum and maximum absolute single-precision values in a single pass and assigns the results to a provided output array.
+
+```javascript
+var Float32Array = require( '@stdlib/array/float32' );
+
+var out = new Float32Array( 2 );
+
+var v = minmaxabsf.assign( 5.0, -1.0, out, 1, 0 );
+// returns <Float32Array>[ 1.0, 5.0 ]
+
+var bool = ( v === out );
+// returns true

+### Usage
+
+```c
+#include "stdlib/math/base/special/minmaxabsf.h"
+```
+
+#### stdlib_base_minmaxabsf( x, y, min, max )
+
+Returns the minimum and maximum absolute single-precision floating-point values in a single pass.
+
+```c
+float min;
+float max;
+stdlib_base_minmaxabsf( -4.2f, 3.14f, &min, &max );
+// [ 3.14, 4.2 ]
+
+stdlib_base_minmaxabsf( 0.0f, -0.0f, &min, &max );
+// [ 0.0, 0.0 ]
+```
+
+The function accepts the following arguments:
+
+-   **x**: `[in] float` input value.
+-   **y**: `[in] float` input value.
+-   **min**: `[in] *float` output min.
+-   **max**: `[in] *float` output max.
+
+```c
+void stdlib_base_minmaxabsf( const float x, const float y, float* min, float* max );
+```
