An online calculator to calculate values of the floor and ceiling functions for a given value of the input x.
The input to the floor function is any real number x and its output is the greatest integer less than or equal to x. The notation for the floor function is: floor(x) = ⌊x⌋
Floor(2.1) = ⌊2.1⌋ = 2
Floor (3) = ⌊3⌋ = 3
Floor (-0.5) = ⌊-0.5⌋ = -1
Floor (0) = ⌊0⌋ = 0
The input to the ceiling function is any real number x and its output is the smallest integer greater than or equal to x. The notation for the ceiling function is: ceil(x) = ⌈x⌉
Ceil(2.1) = ⌈2.1⌉ = 3
ceil(3) = ⌈3⌉ = 3
ceil (-0.5) = ⌈-0.5⌉ = 0
ceil (0) = ⌈0⌉ = 0
Floor(x) = ⌊x⌋ gives the least integer less greater than or equal to x.
