Fast Stirling Numbers of the Second Kind R package logStirling2 version 0.3.0 Provides efficient tools for calculating Stirling numbers of the second kind and their logarithms. Includes an exact arbitrary-precision implementation using 'gmp' that avoids numerical cancellation, a fast C++ backend with internal caching for log-scale calculations, and Temme's asymptotic approximation for very large inputs.
