Adding a thousands separator "˙" to a floating point number

Question

I work with a number of numbers from 0.00 to 9999.99. I need to add thousands separator "˙", so it 1300,00should be 1˙300,00. NSNumberFormatter uses "," as a delimiter, so this is not good for me.

I tried to use

func formatNumber (i: Float) -> String {
    var counter = 0
    var correctedNumber = ""

    if i > 999 {
        for char in "\(i)".characters {
            if counter == 1 {
                correctedNumber += "˙" + "\(char)"
            } else {
                correctedNumber += "\(char)"
            }

            counter++
        }
    } else {
        correctedNumber = "\(i)"
    }

    return correctedNumber
}

but it cannot format decimal numbers.

What is the right way to do this?

Answer 1

You just need to set it up correctly NSNumberFormatter.

let formatter = NSNumberFormatter()
formatter.groupingSeparator = "˙"
formatter.decimalSeparator = ","
formatter.usesGroupingSeparator = true
formatter.minimumFractionDigits = 2

Testing

formatter.stringFromNumber(1300) // "1˙300,00"

Answer 2

decimalSeparator groupingSeparator, , , , .

NSNumberFormatter . ( en-US), , a ..

, , . , , ( ).

, , , :

let formatter = NSNumberFormatter()
formatter.locale = NSLocale(localeIdentifier: "it_IT")
