The function-like macros in math.h don’t deliver a floating type result, so aren't relevant in F.2.2#4. The macros do take floating type arguments so are relevant in F.2.2#6. And they are part of the binding between C and IEC 60559 so are relevant in F.3#1.

To emphasize that C supports IEC 60559. That support is what is detailed in F.3.
