show(length:rounded:increment:)
Creates a display strategy that shows a fractional part.
Declaration
static func show(length: Int, rounded rule: FloatingPointRoundingRule = .toNearestOrEven, increment: Double? = nil) -> Duration.UnitsFormatStyle.FractionalPartDisplayStrategyParameters
- length:
The maximum string length of the fractional part.
- rule:
A rule for rounding fractional values up or down. Defaults to Tonearestoreven.
- increment:
A multiple by which the formatter rounds the fractional part. The formatter produces a value that is an even multiple of this increment. If this parameter is
nil(the default), the formatter doesn’t apply an increment. This value is only meaningful when the combination of allowed units, rounding rule, and formatting strategy requires expressing a unit with a fractional part. For example, a formatter that only allows minutes and uses a strategy with a length of2and default rounding rule formats 40 seconds as0.67 minutes. With aincrementof0.05, the formatter formats this value as0.65 minutesinstead.
