Kotlin: How to call setText() using a Float data type?

Question

How do I call setText() using float data type? I have already tried this

if (response.isSuccessful) {
      val destination = response.body()
      destination?.let {
              client_names.setText(destination.client_name)
              product_names.setText(destination.product_name)

              amounts.setText(String.valueOf(destination.amount)) ----->
              prices.setText(String.valueOf(destination.price))   ----->

              comments.setText(destination.comment)

              collapsing_toolbar.title = destination.client_name + destination.product_name
         }

I have tried this answer from this link

Doesn't a `Float` have a `toString()` method in Kotlin? I think it does... Try that if you haven't already. — deHaar, Jul 13 '20 at 12:20
Have you tried this. https://stackoverflow.com/a/8907890/6264949 This might help you. — Tushar Deshpande, Jul 13 '20 at 12:20
@p2pdops just like this ? amounts.setText(String.valueOf(destination.amount.toString())) — , Jul 13 '20 at 12:21
actually it is better to follow @webfreak answer because you may want to add currency before amount so you can `amounts.setText("Curr: ${destination.amount}")` that would display `Curr: 100` (if destination.amount is 100) — p2pdops, Jul 13 '20 at 12:36

If you don't need any formatting just do:

setText("${destination.amount}")
