MATH.Statistics_LREAL (FB)
(CAA_Mathematics.library)
This function block will update the values of minimum, maximum and average with respect to the integral input parameter
, which will be added to a set of integral data
(stemming from previous calls). The arithmetic mean 
of the values 
is calculated by : 
.
