Abstract This paper analyzes the distribution of trailing digits (tail end digits) of positive real floating-point numbers represented in arbitrary base $\textit{β}$ and randomly chosen from a logarithmic distribution. The analysis shows that the $\textit{n}th$ digit for $\textit{n}$ ≥ 2 is actually approximately uniformly distributed. The approximation depends upon both $\textit{n}$ and the $base\textit{β}.$ It becomes better as $\textit{n}$ increases, and it is exact in the limit as $\textit{n}$ ⇒ ∞. A table of this distribution is presented for various β and $\textit{n},$ along with a table of the maximum digit by digit deviation Δ of the logarithmic distribution from the uniform distribution. Various asymptotic results for Δ are included. These results have application in resolving open questions of Henrici, of Kaneko and Liu, and of Tsao.
