just tell what what text you'd like to see inserted where in the docs and I'll do it.
At this page: http://www.boost.org/doc/libs/1_43_0/doc/html/accumulators/user_s_guide.html... I would add a link sum_kahan pointing to this: =================================================== sum_kahan Implements the summation kahan's algorithm, reducing the accumulation error in case of floating point types. Result Type sample-type Depends On none Variants none Initialization Parameters none Accumulator Parameters none Extractor Parameters none Accumulator Complexity O(1), however compared to naive sum this accumulator performs 4 sum operations for each element accumulated Extractor Complexity O(1) Header #include <boost/accumulators/statistics/sum_kahan.hpp> Example accumulator_set<float, stats<tag::sum_kahan> > acc; BOOST_CHECK_EQUAL(0.0f, sum_kahan(acc)); for (size_t i = 0; i < 1e6; ++i) { acc(1e-6f); } BOOST_CHECK_EQUAL(1.0f, sum_kahan(acc)); ========================================================= I'm not sure if this was what you meant by documentation.
