| Description | mean = (1 / size) * sum( Xi )
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. |

| Return value | Mean of the vector elements (except complex versions in Pascal/Delphi) |
