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

Some Change in Answer(For Int and correct for million):

func formatPoints(num: Int) ->String{
    let thousandNum = num/1000
    let millionNum = num/1000000
    if num >= 1000 && num < 1000000{
        if(thousandNum == thousandNum){
            return("\(thousandNum)k")
        }
        return("\(thousandNum)k")
    }
    if num > 1000000{
        if(millionNum == millionNum){
            return("\(millionNum)M")
        }
        return ("\(millionNum)M")
    }
    else{
        if(num == num){
            return ("\(num)")
        }
        return ("\(num)")
    }

}
