    Purpose of use
    Compare to my calculations within database. I needed to know if my 10+ digits were accurate.
    Are you using the Taylor series? All other methods I have seen are approximations. Some crazy good, but still approximations. We match up to 30 decimals so I assume we're both correct. Thanks for this wonderful tool.

    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
    how we want to make the result 2 not 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.
