Zero mean and unity variance.
Shift and scale the values in a range as: where m is the mean and s is the standard deviation. After normalization, the range will have zero mean and unity variance.

The element in range [result, result + (last-first)) is calculated as result[i] = (first[i] - m) / s where m and std are the mean and standard deviation, respectively, of the range [first, last).
It is possible to centralize a range "in place"; it is permissible for the iterators first and result to be the same.
