+These functions determine whether the total order relationship,
+defined in IEEE 754-2008, is true for the absolute values of @var{x}
+and @var{y}, returning nonzero if it is true and zero if it is false.
+No exceptions are raised even for signaling NaNs.

Not all machines provide hardware support for these operations. On
machines that don't, the macros can be very slow. Therefore, you should
not use these functions when NaN is not a concern.
