A modern programming language that makes developers happier.

kotlinlang

just gonna do this
```
searchResults.sortByDescending {
                    if (it.negotiated_price != null) {
                        100 - ((it.negotiated_price!!.toInt() / it.price) * 100)
                    } else {
                        it.price
                    }
                }
```

Isnt it a bit weird that you are sorting discounts in percentage versus absolute prices ??

`(it.negotiated_price?.toInt() ?: price) / it.price`

Also, `negotiated_price` is named improperly for a variable. It should be named `negotiatedPrice`
