This should say it returns the "smallest integer greater than or equal to a given number", which is subtly different than what currently is listed. It should also indicate the 'int' is the complementary operation.

No, the wording is actually correct, even if the notion of the function goes against the generally accepted definition of the ceiling function.


ceiling(1.1) = 2
ceiling(1.8) = 2
ceiling(2) = 3
