Unusual notation

Hi,

I came across a notation in the text "Mathematical Analysis" by Malik
I can't recall ever seeing. It seems he is defining a function using a
symbol which is like a "left corner", i.e. |__ , so f(x) = |__ where
the argument, x, is on top of the underscore. Since I can't write a
letter with an underscore here, I'll write f(x) = (|__)(x). In neither
the appendices or introduction does he appear to define this notation.

This is in a section about sequences (pg 83, to be specific), where
Malik is defining the members of a sequence {a_n} as :

a_n = ( |__ )(3n) / [(|__)(n)]^3 where n is a natural number.

I'd say it was something like a floor function, but this wouldn't make
any sense in the context of this problem since all of the quantities
he is considering are integers.

Thnaks,
Fran
