short DECIDE__Average(

    * double * Result,
    * const double * DataArray,
    * const short * DataArrayLength,
    * const short * Mode)

Return the average of the DataArrayLength input values

    * mode 1 : arithmetic (sum of all values / DataArrayLength)
    * mode 2 : geometric (root DataArrayLength of the product of all values)
    * mode 3 : quadratic (square root of the average of the square of all values)

return value :

    * 0 : completed sucessfully
    * 1 : null pointer in first parameter
    * 2 : null pointer in second parameter
    * 3 : null pointer in third parameter
    * 3 : null pointer in fourth parameter
    * 101 : DataArrayLength < 1
    * 102 : invalid Mode
