Ceiling
Ceiling[
x
] gives the smallest integer greater than or equal to x.
Mathematical function (see ASection A.3.10).
Examples: Ceiling[2.4]
 ; Ceiling[2.6]
 ; Ceiling[-2.4]
 ; Ceiling[-2.6]
 .
Ceiling[
x
] can be entered in StandardForm as 
x
 , lc
x rc or \[LeftCeiling]
x \[RightCeiling].
Ceiling[
x
] returns an integer when x is any numeric quantity, whether or not it is an explicit number.
Example: Ceiling[Pi^2]
 .
For exact numeric quantities, Ceiling internally uses numerical approximations to establish its result.
