+#### STDLIB_MATH_BASE_NAPI_MODULE_ZZZZ_Z( fcn )
+
+Macro for registering a Node-API module exporting an interface for invoking a quaternary function accepting and returning double-precision complex floating-point numbers.
+
+```c
+#include "stdlib/complex/float64/ctor.h"
+#include "stdlib/complex/float64/reim.h"
+
+static stdlib_complex128_t add( const stdlib_complex128_t w, const stdlib_complex128_t x, const stdlib_complex128_t y, const stdlib_complex128_t z ) {
+    double wre;
+    double wim;
+    double xre;
+    double xim;
+    double yre;
+    double yim;
+    double zre;
+    double zim;
+    double re;
+    double im;
+
+    stdlib_complex128_reim( w, &xre, &wim );
+    stdlib_complex128_reim( x, &yre, &xim );
+    stdlib_complex128_reim( y, &zre, &yim );
+    stdlib_complex128_reim( z, &zre, &zim );

+}
+
+// ...
+
+// Register a Node-API module:
+STDLIB_MATH_BASE_NAPI_MODULE_ZZZZ_Z( add );
+```
+
+The macro expects the following arguments:
+
+-   **fcn**: `stdlib_complex128_t (*fcn)( stdlib_complex128_t, stdlib_complex128_t, stdlib_complex128_t, stdlib_complex128_t )` quaternary function.
+
+When used, this macro should be used **instead of** `NAPI_MODULE`. The macro includes `NAPI_MODULE`, thus ensuring Node-API module registration.
