These five functions scan all variable names that match the given
root name and return the smallest, largest,
summed up and average value, respectively. The datatype of the result is either an integer or float,
depending on the list elements. The standard deviation is calculated using the formula:
StdDev^2 = Sum((ElementX-Mean)^2) / Elements
Example for a simple list:
MyList() = 1,4,-5,10,8,2
Print (count MyList)
Print (min MyList)
Print (max MyList)
Print (sum MyList)
Print (mean MyList)
Print (stddev MyList)
Print (join MyList)
