+## Usage
+
+```javascript
+var minmaxf = require( '@stdlib/math/base/special/minmaxf' );
+```
+
+#### minmaxf( x, y )
+
+Returns the minimum and maximum values in a single pass for single-precision floating-point number.
+
+```javascript
+var v = minmaxf( 4.0, 3.0 );
+// returns <Float32Array>[ 3.0, 4.0 ]
+
+v = minmaxf( +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 = minmaxf( 4.2, NaN );
+// returns <Float32Array>[ NaN, NaN ]
+
+v = minmaxf( NaN, 3.14 );
+// returns <Float32Array>[ NaN, NaN ]
+```
+
+#### minmaxf.assign( x, y, out, stride, offset )
+
+Returns the minimum and maximum values in a single pass and assigns results to a provided output array.
+
+```javascript
+var Float32Array = require( '@stdlib/array/float32' );
+
+var out = new Float32Array( 2 );
+
+var v = minmaxf.assign( 5.0, -2.0, out, 1, 0 );
+// returns <Float32Array>[ -2.0, 5.0 ]
+
+var bool = ( v === out );
+// returns true
+```

+### Usages
+
+```c
+#include "stdlib/math/base/special/minmaxf.h"
+```
+
+#### stdlib_base_minmaxf( x, y, min, max )
+
+Returns the minimum and maximum for single-precision floating-point number.
+
+```c
+float min;
+float max;
+stdlib_base_minmaxf( 3.2, 4.1, &min, &max );
+
+stdlib_base_minmaxf( 0.0f, -0.0f, &min, &max );
+```
+
+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_minmaxf( const float x, const float y, float* min, float* max );
+```
