Consider the division function, 
,
The evaluation of 
,
proceeds as follows:
The sign of 
and 
are determined
by the arguments and the relationship with the
second derivative of 
:
The corresponding evaluation with constant intervals
produces a noticeably larger result:
Similar behaviour may be observed near the origin with the general
exponentiation function, 
.
