[Boost-users] [accumulators] Help with accumulator-based typedef

Hello, I am trying to setup a "simple" weighted_mean accumulator for a struct I want to accumulate. It goes something like this. Let's call it a float for sake of example. It's actually a struct with mathematical comprehension: addable, subtractable, multipliable, dividable, and so on. typedef accumulator_settag::rolling_mean, features > my_float_accumulator_set; However, I am getting obscenely long errors complaining about AccumulatorSet, etc, etc. Can someone direct me to a (somewhat) complete example of a weighted_sum accumulator in action? Am I even on the right track type-defining my accumulator ahead of time? Regards, Michael Powell
