Do you really need to parenthesize the parameters? Is there something that can break the variable declaration into multiple statements?

Here, no. It's just a habit or common style guideline to always parenthesize macro parameters since so many macros can otherwise break.

Here, probably not (with proper arguments at least; without the parens something like `MAX(1;2, 3)` would compile without errors though), but I'm just used to doing it everywhere.
