### the_exact_sum_of_a_pool_of_cancelling_values_is_not_the_sum_of_rounded_parts
An exactness test needs inputs whose float sum is inexact and no NaN. `1e16 + 1.0 - 1e16` rounded part
by part is `0.0`; pooled exactly it is `1.0`. This pins the fixture rather than the code.
by part is `0.0`; pooled exactly it is `1.0`. The merge runs in both orders, so whichever part a rival
rounds is the inexact one: rounding only the other part, only self, or both each fail it (the first
version merged one way and a rival rounding only the exact part passed it; Opus caught that).
