Format number using decimal format in kotlin

I am facing an issue where I need to do some calculations with a number like for example 5000,00 multiplied it by (1,025^3).

So in this case 5000,00 * (1,025^3) = 5385,45

So my question is, how can I format the number 5385,45 to be like 5.385,45 using decimal format maybe?

I tried by myself and I did this piece of code that outputs 5385,45 in the app but not 5.385,45

    var interestValue = (5000,00*(Math.pow(1.025,yearValue)))
    val number = java.lang.Double.valueOf(interestValue)
    val dec = DecimalFormat("#,00")
    val credits = dec.format(number)
    vValueInterest.text = credits
Solution

  • This is the format you need:

    val dec = DecimalFormat("#,###.##")

    will print:

    5.384,45

    if you need always exactly 2 digits after the decimal point:

    val dec = DecimalFormat("#,###.00")
