Swift 2.0 Format 1000's into a friendly K's

Question

I\'m trying to write a function to present thousands and millions into K\'s and M\'s For instance:

1000 = 1k
1100 = 1.1k
15000 = 15k
115000 = 115k
1000000 =          


        

Answer 1

I have converted @AnBisw's answer to use switch (build time friendly):

   extension Double {
    var kmFormatted: String {
        switch self {
        case ..<1_000:
            return String(format: "%.0f", locale: Locale.current, self)
        case 1_000 ..< 999_999:
            return String(format: "%.1fK", locale: Locale.current, self / 1_000).replacingOccurrences(of: ".0", with: "")
        default:
            return String(format: "%.1fM", locale: Locale.current, self / 1_000_000).replacingOccurrences(of: ".0", with: "")
        }
    }
}
