Range mapping
Declaration
Swift
public func scaled(from source: ClosedRange<Self>, to destination: ClosedRange<Self>, clamped: Bool = false, reversed: Bool = false) -> Self
Parameters
source
source range
destination
destination range
clamped
specify true to clamp result in destination range
reversed
specify true to reverse result
Return Value
By mapping source range to destination, result goes from destination lower bound, to destination upper bound once the phase hits source upper bound
