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 > <[email protected]> a écrit : > > >> On 25 Jun 2016, at 11:06, Karl via swift-evolution >> <[email protected] <mailto:[email protected]>> 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? I know floor and ceiling are pretty common terms, but they're > just a form rounding when it comes down to it. > _______________________________________________ > swift-evolution mailing list > [email protected] > https://lists.swift.org/mailman/listinfo/swift-evolution
