    Purpose of use
    how to make calculation if the single give 1,-1

    if we do the calculation
    1+1+1+ = 3 but,
    what if 1 +(-1)+1 = 1

    Purpose of use
    Get upper cumulative for very large deviations (6 sigma to 8 sigma). This calculator has the required large number of digits
    Why number of standard deviations (which works perfectly well in this box) is titled "percentile". It is not percentile as I understand it.
