-Package \bnumname provides |\thebnumexpr...\relax| which is analogous to
-|\the\numexpr...\relax|, while allowing arbitrarily big integers, powers,
-factorials, floored division, modulo, and comma separated expressions.
+Package \bnumname provides |\thebnumexpr|\marg{expression}|\relax| which is
+analogous to |\the\numexpr|\marg{expression}|\relax|, with these extensions:
+\begin{itemize}
+\item it allows arbitrarily big integers,
+\item it computes powers (with either |**| or |^| as infix operator),
+\item it computes factorials (with |!| as postfix operator),
+\item it has an operator |//| for floored division and |/:| for the
+  associated modulo,
+\item the space character can be used to separate in the source blocks of
+digits for better readability of long numbers,
+\item since |1.2b| the underscore |_| may also be used as visual digit
+  separator,
+\item comma separated expressions are allowed.
+\end{itemize}
+It expands completely, but in two steps (whereas
+|\the\numexpr|\marg{expression}|\relax| expands in one step only, and
+|\numexpr| by itself is not expandable).
+
+|1.2d| adds a |\bnumeval|\marg{expression} interface. The |\bnumeval| macro
+also expands completely in two steps.
+
