It's a mathematical notation that anyone using this page should understand because it comes with the territory. Once you are touching doubles, soon you'll be looking at functions in libm proper, where this type of notation is even more common. Will you then propose to change all those as well? I think understanding the landscape's notation is a requirement, and we don't need to say things a 2nd time in baby talk.
