If you don’t need any formatting just do:

setText("${destination.amount}")

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
