In the docs for
kotlin.math.ceil()
it says it returns:

the smallest double value that is greater than the given value
x
and is a mathematical integer

~~Shouldn't it say:~~

the smallest double value that is greater than or equal to the given value
x
and is a mathematical integer

(similar with
floor
, but obviously the other way around) EDIT: The documentation is actually correct, I just need to learn to read (thanks @karelpeeters)

You could argue that the documentation is correct, it just treats integers as a special case:

Special cases:

-
ceil(x)
is
x
where
x
is
NaN
or
+Inf
or
-Inf
or already a mathematical integer.

But I agree that it's confusing.

or already a mathematical integer

We'll clarify summary so that it is clear without delving into special cases. https://youtrack.jetbrains.com/issue/KT-30418
