1. ## the [[x]] notation

So I have a calculus problem with [[t]] in it. ( The problem is "What is the limit as t approaches 2 from the left of ([[t]]-t)" for context )

I have no clue what this notation means, 'greatest something or other'. Can anyone help me out?

Probably the nearest integer function. Look it up.
