Hi, I don't know why there is not such a class in JDK. Maybe because BigDecimal and BigInteger are objects not primitives therefore they can have null value. I believe that that package should contains BigDecimalStatistics, BigIntegerStatistics and tools for downstreams collectors in order to performe some downstream operations like averagingInt in JDK. I've already started implementing BigDecimalStatistics on my fork but I haven't pushed those changes on my fork
