Ansus Wrote:Great! Now it works, but only for a limited range of bases. Particularly it works for the base \( \sqrt{2} \). I used this formula:
\( \operatorname{slog}_b(x)=\lim_{n\to\infty} \frac{\ln \left(\frac{\frac{W(-\ln b )}{\ln b}+\exp_b^{[n]}(x)}{\frac{W(-\ln b)}{\ln b}+\exp_b^{[n]}(1)}\right)}{\ln \ln \left(\frac{W(-\ln b)}{-\ln b}\right)} \)
I've added this formula to our wiki page:
