pub fn sums_to(
values: impl IntoIterator<Item = f64>,
target: f64,
tolerance: f64,
) -> (bool, f64)Expand description
Whether the values yielded by values sum to target within ± tolerance (percentage points). Returns the computed sum alongside the
verdict, since callers reporting a failure need it in their message. A
non-finite sum (e.g. one input was NaN) is always false.
