Least Integer Function

The function whose value at any number x is the smallest integer greater than of equal to x is called the least integer function. It is denoted by ⌈x⌉ It is also known as ceiling of x. For example ⌈3.578⌉ = 4 , ⌈0.78⌉ = 1 , ⌈-4.64⌉ = - 4.

The graph of the least integer function lies on or above the line y = x , so it provides an integer ceiling for x.
