+### Usage
+
+```c
+#include "stdlib/math/base/special/invf.h"
+```
+
+#### stdlib_base_invf( x )
+
+Computes the multiplicative inverse of a single-precision floating-point number.
+
+```c
+float y = stdlib_base_invf( 2.0f );
+// returns 0.5f
+```
+
+The function accepts the following arguments:
+
+-   **x**: `[in] float` input value.
+
+```c
+float stdlib_base_inv( const float x );
+```
