+### Usage
+
+```c
+#include "stdlib/math/base/assert/int32_is_odd.h"
+```
+
+#### stdlib_base_int32_is_odd( x )
+
+Tests if a 32-bit integer is odd.
+
+```c
+#include
+
+bool out = stdlib_base_int32_is_odd( 5 );
+// returns true
+
+out = stdlib_base_int32_is_odd( -2 );
+// returns false
+```
+
+The function accepts the following arguments:
+
+- **x**: `[in] double` input value.
+
+```c
+bool stdlib_base_int32_is_odd( const double x );
+```
