Syntax
Parameters
x-
A number.
Return value
The smallest integer greater than or equal to x. It's the same value as -Math.floor(-x).
Description
Because ceil() is a static method of Math, you always use it as Math.ceil(), rather than as a method of a Math object you created (Math is not a constructor).
