final case class KahanSum(sum: Double = 0, c: Double = 0) extends Product with Serializable

Aggregator state.

sum

the accumulator

c

a running compensation for lost low-order bits

Note

cannot use generics for double vs float due to perf: https://stackoverflow.com/questions/4753629/how-do-i-make-a-class-generic-for-all-numeric-types
