+#### STDLIB_MATH_BASE_NAPI_MODULE_FII_F( fcn )
+
+Macro for registering a Node-API module exporting an interface for invoking a ternary function accepting a single-precision floating-point number and two signed 32-bit integers and returning a single-precision floating-point number.
+
+```c
+#include <stdint.h>
+
+static float fcn( const float x, const int32_t y, const int32_t z ) {
+    // ...
+}
+
+// ...
+
+// Register a Node-API module:
+STDLIB_MATH_BASE_NAPI_MODULE_FII_F( fcn );
+```
+
+The macro expects the following arguments:
+
+-   **fcn**: `float (*fcn)( float, int32_t, int32_t )` ternary function.
+
+When used, this macro should be used **instead of** `NAPI_MODULE`. The macro includes `NAPI_MODULE`, thus ensuring Node-API module registration.
