The greatest integer function which is also known as a floor function rounds any number down to the nearest integer.

for example--

If -2 ≤x <-1 then value of function is -2

If -1 ≤x < 0 then value of function is -1

If 0 ≤x < 1 then value of function is 0

If 1 ≤x < 2 then value of function is 1

and so on.

Similarly the least integer function which is also known as a ceiling function rounds any number up to the nearest integer.

for example--

If -2 < x ≤ -1 then value of function is -1

If -1 < x ≤ 0 then value of function is 0

If 0 < x ≤ 1 then value of function is 1

If 1 < x ≤ 2 then value of function is 2

and so on.
