Whatever the naming scheme, I would be hesitant to have the non-mutating versions of floor and ceil have different endings, seeing how connected they are. So:
floor, ceil floored, ceiled flooring, ceiling But not a mix. > On 27 Jun 2016, at 07:13, Xiaodi Wu via swift-evolution > <[email protected]> wrote: > >> On Mon, Jun 27, 2016 at 12:45 AM, Charlie Monroe via swift-evolution >> <[email protected]> wrote: >> Given the API guidelines, it should be >> >> rounded, ceiled, floored >> >> for returning the rounded/ceiled/floored value and >> >> round(), ceil(), floor() >> >> would be the mutating variants.
