The maximum or greatest integer function of a real number x is represented as [x].
Now for all values of x, the maximum integer function returns the largest integer less than or equal to x.
i.e. the maximum integer function rounds down to a real number to the nearest integer.
Example: [2] = 2, [1.4] = 1, [3.8] = 3, [2.5] = 2, [-3] = -3, [-1.7] = - 2, [-2.2] = -3, [-4.5] = -5, etc.
