Fields
Statistics Group
Specifies the statistics group to be used in the formula calculation.
Divide by Zero Treatment
Provides instructions to the NAC on the course of action to take whenever a
'divide-by-zero' calculation is made.
Force to zero
Select this option to force the result of such a division to become zero.
For example, division by zero can occur when there are no incoming
calls. The average answering delay for any given period is equal to
total answer delay/calls answered. If no calls were answered, this
division results in a variable impossible to express. (Of course, total
answer delay is also zero, but zero divided by zero still results in an
error.) In cases like this, "Force to zero" can be selected since the
average answering delay was effectively zero.
