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. Question is where it's not too confusing for anyone knowing these from another language. > On Jun 25, 2016, at 9:02 PM, Remy Demarest via swift-evolution > <swift-evolution@swift.org> wrote: > > We don't seem to have a rounded() function either as part of FloatingPoint, > we should probably have these methods in the end: > > func rounded() -> Self > func rounded(withPrecision: Int) -> Self > > Along with the 4 other methods proposed below. > >> Le 25 juin 2016 à 11:55, Haravikk via swift-evolution >> <swift-evolution@swift.org <mailto:swift-evolution@swift.org>> a écrit : >> >> >>> On 25 Jun 2016, at 11:06, Karl via swift-evolution >>> <swift-evolution@swift.org <mailto:swift-evolution@swift.org>> wrote: >>> >>> floor() and ceil(), exactly like C. ceiling() is more descriptive and is a >>> mathematical term of art >>> <http://mathworld.wolfram.com/CeilingFunction.html>. >>> nextIntegralUp() and nextIntegralDown() are more descriptive still, but >>> possibly misleading as (4.0).nextIntegralUp() == 4.0 >> I'm in favour of these capabilities being there, but in terms of naming I've >> often wondered why it can't just be part of a rounding group of methods like >> so: >> >> func roundedUp() -> Self { … } >> func roundedUp(withPrecision:Int) -> Self { … } >> func roundedDown() -> Self { … } >> func roundedDown(withPrecision:Int) -> Self { … } >> >> Since the methods with implied precision of zero are equivalent to floor and >> ceiling surely?
