Given Eq[A], return a PartialOrder[A] using the combine
operator to determine the partial ordering. This method assumes
combine
functions as join
(that is, as an upper bound).
Given Eq[A], return a PartialOrder[A] using the combine
operator to determine the partial ordering. This method assumes
combine
functions as join
(that is, as an upper bound).
This method returns:
0.0 if x = y -1.0 if y = combine(x, y) 1.0 if x = combine(x, y) NaN otherwise

Given Eq[A], return a PartialOrder[A] using the combine
operator to determine the partial ordering. This method assumes
combine
functions as meet

Given a sequence of as
, sum them using the monoid and return the total.
Example:
scala> import cats.kernel.instances.string._
scala> Monoid[String].combineAll(List("One ", "Two ", "Three"))
res0: String = One Two Three
scala> Monoid[String].combineAll(List.empty)
res1: String = ""
