Sasha 1dcdb07d30 promql: use Kahan summation for Native Histograms (#15687) ... As for float samples, Kahan summation is used for the `sum` and `avg` aggregation and for the respective `_over_time` functions. Kahan summation is not perfect. This commit also adds tests that even Kahan summation cannot reliably pass. These tests are commented out. Note that the behavior might be different on other hardware platforms. We have to keep an eye on test failing on other hardware platforms and adjust them accordingly. Signed-off-by: Aleksandr Smirnov <5targazer@mail.ru>		3 months ago
