Swift - How to remove a decimal from a float if the decimal is equal to 0?

Question

I'm displaying a distance with one decimal, and I would like to remove this decimal in case it is equal to 0 (ex: 1200.0Km), how could I do that in swift? I'm displaying this number like this:

let distanceFloat: Float = (currentUser.distance! as NSString).floatValue distanceLabel.text = String(format: "%.1f", distanceFloat) + "Km" 

Answer 1

Swift 3/4:

var distanceFloat1: Float = 5.0 var distanceFloat2: Float = 5.540 var distanceFloat3: Float = 5.03  extension Float {     var clean: String {        return self.truncatingRemainder(dividingBy: 1) == 0 ? String(format: "%.0f", self) : String(self)     } }  print("Value \(distanceFloat1.clean)") // 5 print("Value \(distanceFloat2.clean)") // 5.54 print("Value \(distanceFloat3.clean)") // 5.03 

Swift 2 (Original answer)

let distanceFloat: Float = (currentUser.distance! as NSString).floatValue distanceLabel.text = String(format: distanceFloat == floor(distanceFloat) ? “%.0f" : "%.1f", distanceFloat) + "Km" 

Or as an extension:

extension Float {     var clean: String {         return self % 1 == 0 ? String(format: "%.0f", self) : String(self)     } }
