+#### STDLIB_MATH_BASE_NAPI_MODULE_CCCC_C( fcn )
+
+Macro for registering a Node-API module exporting an interface for invoking a quaternary function accepting and returning single-precision complex floating-point numbers.
+
+```c
+#include "stdlib/complex/float32/ctor.h"
+#include "stdlib/complex/float32/reim.h"
+
+static stdlib_complex64_t add( const stdlib_complex64_t w, const stdlib_complex64_t x, const stdlib_complex64_t y, const stdlib_complex64_t z ) {
+    float wre;
+    float wim;
+    float xre;
+    float xim;
+    float yre;
+    float yim;
+    float zre;
+    float zim;
+    float re;
+    float im;
+
+    stdlib_complex64_reim( w, &wre, &wim );
+    stdlib_complex64_reim( x, &xre, &xim );
+    stdlib_complex64_reim( y, &yre, &yim );
+    stdlib_complex64_reim( z, &zre, &zim );
+
+    re = wre + xre + yre + zre;
+    im = wim + xim + yim + zim;
+
+    return stdlib_complex64( re, im );
+}
+
+// ...
+
+// Register a Node-API module:
+STDLIB_MATH_BASE_NAPI_MODULE_CCCC_C( add );
+```
+
+The macro expects the following arguments:
+
+-   **fcn**: `stdlib_complex64_t (*fcn)( stdlib_complex64_t, stdlib_complex64_t, stdlib_complex64_t, stdlib_complex64_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.

+napi_value addon( napi_env env, napi_callback_info info ) {
+    return stdlib_math_base_napi_cccc_c( env, info, add );
+}
+
+// ...
+```
+
+The function accepts the following arguments:
+
+-   **env**: `[in] napi_env` environment under which the function is invoked.
+-   **info**: `[in] napi_callback_info` callback data.
+-   **fcn**: `[in] stdlib_complex64_t (*fcn)( stdlib_complex64_t, stdlib_complex64_t, stdlib_complex64_t, stdlib_complex64_t )` quaternary function.
+
+```c
