DoubleTotalOrderTrait

trait DoubleTotalOrderTrait extends Order[Double] with Hash[Double]

An Order[Double] instance which produces a total order by ordering NaNs above all other Doubles

Contrary to the specification of cats, the DoubleOrdering in cats.kernel is not total because NaN is not ordered (all comparisons return false). This behaviour is consistent with IEEE-754, but not very practical.

java.lang.Double.compare orders NaN to be largest of all Doubles.
