+## Usage
+
+```javascript
+var wrapf = require( '@stdlib/math/base/special/wrapf' );
+```
+
+#### wrapf( v, min, max )
+
+Wraps a value on the half-open interval `[min,max)`.
+
+```javascript
+var v = wrapf( 3.14, 0.0, 5.0 );
+// returns ~3.14
+
+v = wrapf( -3.14, 0.0, 5.0 );
+// returns ~1.86
+
+v = wrapf( 10.0, 0.0, 5.0 );
+// returns 0.0
+
+v = wrapf( -0.0, 0.0, 5.0 );
+// returns 0.0
+
+v = wrapf( 0.0, -3.14, -0.0 );
+// returns ~-3.14
+```
+
+If provided `NaN` for any argument, the function returns `NaN`.
+
+```javascript
+var v = wrapf( NaN, 0.0, 5.0 );
+// returns NaN
+
+v = wrapf( 0.0, NaN, 5.0 );
+// returns NaN
+
+v = wrapf( 3.14, 0.0, NaN );
+// returns NaN
+```
+
+If provided `min == max`, the function returns `NaN`.
+
+```javascript
+var v = wrapf( 3.14, 3.0, 3.0 );
+// returns NaN
+```

+### Usage
+
+```c
+#include "stdlib/math/base/special/wrapf.h"
+```
+
+#### stdlib_base_wrapf( v, min, max )
+
+Wraps a value on the half-open interval `[min,max)`.
+
+```c
+float v = stdlib_base_wrapf( 3.14, 0.0, 5.0 );
+// returns ~3.14
+
+v = stdlib_base_wrapf( -3.14, 0.0, 5.0 );
+// returns ~1.86
+```
+
+The function accepts the following arguments:
+
+-   **v**: `[in] float` input value to wrap.
+-   **min**: `[in] float` minimum value.
+-   **max**: `[in] float` maximum value.
+
+```c
+float stdlib_base_wrapf( const float v, const float min, const float max )
+```
