+### Usage
+
+```c
+#include "stdlib/math/base/special/minn.h"
+```
+
+#### stdlib_base_minn( count, values )
+
+Returns the minimum value.
+
+```c
+double vals1[] = {4.2};
+double v = stdlib_base_minn( 1, vals1 );
+// returns 4.2
+
+double vals2[] = {3.14, 4.2};
+v = stdlib_base_minn( 2, vals2 );
+// returns 3.14
+```
+
+The function accepts the following arguments:
+
+-   **count**: `[in] int` input value.
+-   **values**: `[in] doubles*` input value.
+
+```c
+float stdlib_base_minn( int count, const double* values );
+```
