**1.Greatest Integer Function**– This is an interesting function. It is defined as the largest integer less than or equal to x

* y*

**= [**

*x*].For all real numbers, *x*, this function gives the largest integer less

than or equal to *x*.

For example: ** [1] = 1 [2.5] = 2 [4.7] = 4 [5.3] = 5**

*Beware!*** [-2] = -2 [-2.6] = -3 [-4.1] = -5 [-6.5] = -7**
