Detailed Description

template<class R>
struct uni20::log_gamma_result< R >

Analytic log-Gamma value, truncation bound and heuristic roundoff indicator.

The bound is evaluated in ordinary arithmetic, not interval arithmetic. It bounds omitted series in exact arithmetic; the roundoff indicator is a separate heuristic, not a correctness certificate. All scalar fields have the context's requested precision. terms counts included Stirling coefficients; shifts counts common recurrence steps.
