int16_t in the Reference section

As a programming newbie, I've come across the declaration int16_t n; and related forms in a number of example code segments but so far not found them described in the reference section.

I've searched for and now understand what they mean but could they be put into the reference section to help beginners please?

TIA Bob

These definitions are not Arduino-specific.

AWOL:
These definitions are not Arduino-specific.

Ok but neither are a good number of other things in the reference section Arduino specific?

Yes, but creating a full reference to everything C++ would bloat the Arduino reference terribly. There are already so many good C++ references around. Why create another here? Maybe the reference section should include some links to larger C++ reference material.
