+#### maxf( x, y )
+
+Returns the maximum single-precision floating-point number.

+var v = maxf( 4.2, 3.14 );

+## Notes
+
+-   The implementation **ignores** the sign of `0`.
+
+    ```javascript
+    var v = maxf( +0.0, -0.0 );
+    // returns -0.0
+
+    v = maxf( -0.0, +0.0 );
+    // returns +0.0
+    ```
+
+-   The implementation does **not** check for `NaN` arguments.
+
+    ```javascript
+    var v = maxf( 3.14, NaN );
+    // returns NaN
+
+    v = maxf( NaN, 3.14 );
+    // returns ~3.14

+### Usage
+
+```c
+#include "stdlib/math/base/special/fast/maxf.h"
+```
+
+#### stdlib_base_fast_maxf( x, y )
+
+Returns the maximum single-precision floating-point number.
+
+```c
+float out = stdlib_base_fast_maxf( 4.2f, 3.14f );
+// returns 4.2f
+
+out = stdlib_base_fast_maxf( 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_fast_maxf( const float x, const float y );
