Just completed the GDNative tutorial for C. But how do I send a value to the c function?

Hi, I have a c function which does some math calculation (takes a float, does some calculations and returns a float).
I want to call this function from GDScript of my KinematicBody object.
I followed the GDNative tutorial here : https://docs.godotengine.org/en/stable/tutorials/plugins/gdnative/gdnative-c-example.html
In this tutorial, the string "World from GDScript" is sent from the c file to GDScript.
But how do I send a value to the c function and then get a value back from that?

I haven't spent much time on GDNative yet, but my naive understanding is that passing parameter to the GDNative-provided method would cause them to show up via the native-side parameters named p_num_args and p_args in the C example. Have you tried checking to see what you get there when passing value in?
