What is the difference in this ( bracket and [ bracket when writing range?

( bracket is known as ipen bracket. It is used when the last number is not included. For example (2,5), in this we will consider everything between w and 5 but not 2 and 5. We will even consider 2.01,etc. For [ bracket which is known as close bracket, will include evereything including 2 and 5 for the example [2,5]
