Question

Which is the greatest integer?

Answer 1

The Greatest Integer Function is denoted by y = [x].

For all real numbers, x, the greatest integer function returns the largest integer
less than or equal to x. In essence, it rounds down a real number to the nearest integer.

For example: [1] = 1 [1.5] = 1 [3.7] = 3 [4.3] = 4
Beware! [-2] = -2 [-1.6] = -2 [-2.1] = -3 [-5.5] = -6
