Actually, your replies helped. I was not aware or in the mindset that branchless_clip was a generally used method for clamping fixed or floating point values. Because of that, I was limiting my searches to gnuradio related stuff (googling "gnuradio branchless_clip"). Now I know it is a general method of doing something.

Helping people who are getting comfortable is a good thing to do. It will ensure they use the tools. There is a limit to this of course. No one wants to see basic level questions being asked all day. 

Another thing you can always do is create a simple test project to call a function or block that you don't understand and see what outputs different kinds of inputs produce. It can be a pain to do this kind of thing, especially with a C++ project where the basic setup is more complicated than a simple Python script, but it's good education anyways.

Also, to re-up Marin's comment, when you've run into these situations where the documentation on something like this is lacking, please feel free to submit patches with better docs to help explain it to others.

I think that at the end of the day, questions like this boil down to "how do I get comfortable with the tools of the trade in software development".

That's not something that the Gnu Radio community can economically address.
