+### Usage
+
+```c
+#include "stdlib/math/base/special/minmax.h"
+```
+
+#### stdlib_base_minmax( x, y, &min, &max )
+
+Returns the minimum and maximum value.
+
+```c
+#include <stdint.h>
+
+double min;
+double max;
+
+stdlib_base_minmax( 4.0, -5.0, &min, &max );
+```
+
+The function accepts the following arguments:
+
+-   **x**: `[in] double` input value.
+-   **y**: `[in] double` input value.
+-   **min**: `[out] double` destination for minimum value.
+-   **max**: `[out] double` destination for maximum value.
+
+```c
+void stdlib_base_minmax( const double x, const double y, double* min, double* max );
+```
