fn order_log_sums<const SLOPE: bool>(
v: f64,
order: i32,
s: f64,
frac_cot: f64,
) -> Result<OrderSums>Expand description
The logarithmic sums of order_series with n - μ = pivot, in three phases like
log_series: direct terms for k <= n - μ, the cancelled pole at k = n - μ + 1, and the
reflected digamma beyond. One division per term serves all reciprocals.
