+.SH DESCRIPTION
+The
+.BR libj2_j2i_is_min ()
+function checks whether
+.I a
+is the largest negative number.

+The
+.BR libj2_j2u_is_min ()
+function is identical to the
+.BR libj2_j2u_is_zero ()
+function, since
+.I a
+cannot be negative for it because
+it is unsigned.
+.PP
+.I a
+is assumed to be
+.RI non- NULL .
+
+.SH RETURN VALUE

+.I a
+is the minimum representable value,
+and 0 otherwise.
+
+.SH ERRORS
+The functions cannot fail.
