+### Usage
+
+```c
+#include "stdlib/number/float32/base/signbit.h"
+```
+
+#### stdlib_base_float32_signbit( x )
+
+Returns a `boolean` indicating if the sign bit for a [single-precision floating-point number][ieee754] is on (`true`) or off (`false`).
+
+```c
+#include <stdint.h>
+
+bool out = stdlib_base_float32_signbit( -3.14f );
+```
+
+The function accepts the following arguments:
+
+-   **x**: `[in] float` input value.
+
+```c
+bool stdlib_base_float32_signbit( const float x );
+```
