+## Usage
+
+```javascript
+var minabsf = require( '@stdlib/math/base/special/minabsf' );
+```
+
+#### minabsf( x, y )
+
+Returns the minimum absolute single-precision floating-point number.
+
+```javascript
+var v = minabsf( -4.2, 3.14 );
+// returns ~3.14
+
+v = minabsf( +0.0, -0.0 );
+// returns +0.0
+```
+
+If any argument is `NaN`, the function returns `NaN`.
+
+```javascript
+var v = minabsf( 4.2, NaN );
+// returns NaN
+
+v = minabsf( NaN, 3.14 );
+// returns NaN

+### Usage
+
+```c
+#include "stdlib/math/base/special/minabsf.h"
+```
+
+#### stdlib_base_minabsf( x, y )
+
+Returns the minimum absolute single-precision floating-point number.
+
+```c
+float out = stdlib_base_minabsf( -4.2f, 3.14f );
+// returns 3.14f
+
+out = stdlib_base_minabsf( 0.0f, -0.0f );
+// returns +0.0f
+```
+
+The function accepts the following arguments:
+
+-   **x**: `[in] float` input value.
+-   **y**: `[in] float` input value.
+
+```c
+float stdlib_base_minabsf( const float x, const float y );
