+Also available in that case is a small extension to \texttt{printf(3)} to print
+a big integer in a formated way. Not every formating is supported (e.g.: no
+thousands separator) but normal alignment works well.
+
+Modifiers are \texttt{Z} for a big integer \texttt{M} for a \texttt{mp\_digit} and
+\texttt{N} to print the array \texttt{a->dp} of a \texttt{mp\_int a}.
+
+Specifiers are \texttt{d, x, o, b, @} for decimal, hexadecimal, octal, binary, and
+base-64 representations respectively. These specifiers are bound to the extensions
+but can be unregistered individually or all together
+
+See example below for the necessary details.
+
+This functions are not threadsafe!

+
+printf("Limb decimal: %Md \textbackslash{}n", a.dp[0]);
+printf("Limb hexdecimal: %Mx \textbackslash{}n", a.dp[0]);
+/* and so on */

+printf("Array decimal: %Nd \textbackslash{}n", &a);
