Greatest Integer Function

The function, or rule which produces the "greatest integer less than or equal to the number" operated upon, is known as greatest integer function. It is denoted by symbol ⌊⌋ , i.e. ⌊x⌋≤x. It is also known as floor of x. Thus ⌊4.5778⌋=4 , ⌊0.75⌋=0 , ⌊-8.7275⌋=-9.

The Graph of the greatest integer function lies on or below the line y = x so it provides an integer floor for x.
