.sp
A total ordering function over the set elements\&.
This is a two\-argument function 
.ft B
f
.ft R
such that
.ft B
f e1 e2
.ft R
is zero if the elements 
.ft B
e1
.ft R
and 
.ft B
e2
.ft R
are equal,
.ft B
f e1 e2
.ft R
is strictly negative if 
.ft B
e1
.ft R
is smaller than 
.ft B
e2
.ft R
,
and 
.ft B
f e1 e2
.ft R
is strictly positive if 
.ft B
e1
.ft R
is greater than 
.ft B
e2
.ft R
\&.
Example: a suitable ordering function is the generic structural
comparison function 
.ft B
compare
.ft R
\&.
