Code samples
This section contains examples of using math.ceil.
Example 1
This example returns the ceil of a whole number.
math.ceil(2.000000) = 2
Example 2
This example returns the ceil of a negative number.
math.ceil(0-1.200000) = -1
Example 3
This example returns 0 as the ceil of a number that is too big for a 64 bit integer.
math.ceil(184467440737095516160.0) = 0
