[Description]
Checks whether the argument is unsigned infinity or Not_a_Number.

[Explanation]
is_uinf_or_nan returns <A HREF="$$LINK(alloc.h/Bool)">TRUE</A> if <I>x</I> is
<A HREF="$$LINK(timath.h/UNSIGNED_INF)">UNSIGNED_INF</A> or <A HREF="$$LINK(timath.h/NAN)">NAN</A>,
else returns <A HREF="$$LINK(alloc.h/Bool)">FALSE</A>. These two special numbers
are treated very similarly in TIOS. This function is an alias for
TIOS function originally called
<A HREF="$$LINK(timath.h/is_float_unsigned_inf_or_nan)">is_float_unsigned_inf_or_nan</A>.
