Math.ceil()
syntax: |
Math.ceil(x) |
where: |
x - any number or numeric expression.
|
return: |
number - the smallest number that is not less than the argument and is equal to a mathematical integer.
|
description: |
If the argument is already an integer, the result is the argument itself. Returns NaN if x cannot be converted to a number.
|
example: |
//The smallest number that is //not less than the argument and is //equal to a mathematical integer is returned //in the following function: function compute_small_arg_eq_to_int(x) { return Math.ceil(x) } |
