Essentially, the greatest integer function takes a number and rounds it down to the nearest integer. Greatest integer function isnt continuous at the integers level and any function which is discontinuous at the integer value, will be nondifferentiable at that point. As the value jumps at each integral value, therefore, it is discontinuous at each integral value. Symbolically, the greatest integer function is written {eq}f(x) = \lfloor x \rfloor {/eq}.
