    |No implicit Ordering defined for B..
    |I found:
    |
    |    scala.math.Ordering.comparatorToOrdering[B](
    |      /* missing */summon[java.util.Comparator[B]])
    |
    |But no implicit values were found that match type java.util.Comparator[B]
    |
    |where:    B is a type variable with constraint >: Double | Long
    |.
    |
    |One of the following imports might make progress towards fixing the problem:
    |
    |  import scala.math.Ordering.comparatorToOrdering
    |  import scala.math.Ordering.ordered
