+
+Macro for registering a Node-API module exporting an interface invoking a binary function accepting a single-precision complex floating-point number and a single-precision floating-point number and returning a single-precision complex floating-point number.
+
+```c
+#include "stdlib/complex/float32/ctor.h"
+#include "stdlib/complex/float32/reim.h"
+
+static stdlib_complex64_t mul( const float y, const stdlib_complex64_t x ) {

+}
+
+// ...
+
+// Register a Node-API module:
+STDLIB_MATH_BASE_NAPI_MODULE_FC_C( mul );
+```
+
+The macro expects the following arguments:
+
+-   **fcn**: `stdlib_complex64_t (*fcn)( float, stdlib_complex64_t )` binary function.
+
+When used, this macro should be used **instead of** `NAPI_MODULE`. The macro includes `NAPI_MODULE`, thus ensuring Node-API module registration.
