Integer versions: the mean of a distribution consisting of whole numbers generally is a fractional, i.e. a floating-point number. Therefore, the return value of the 8, 16, and 32-bit integer versions is a double. For the 64-bit integer version, VQI_mean, the return value is an extended.
Error handlingnone
Return valueMean of the vector elements (except complex versions in Pascal/Delphi)
