Review comment:
Hmm, "trunc" and "ceil" are common API names for this, for example [in
C](https://pubs.opengroup.org/onlinepubs/9699919799/functions/ceil.html),
[Python](https://docs.python.org/3/library/math.html#math.ceil) or
[Rust](https://doc.rust-lang.org/std/primitive.f64.html#method.ceil), so
perhaps keep those names here?
