It calculates no point but a single value. 2. The line does not intersect the y-values but the y-axis. 3.

NORMDIST | Last Parameter has type Logical and is optional | Last Parameter has type Number and is required | Change implementation, Issue 100119 | integrated in OOo3.2 | |

Accuracy is insufficient for x<−2 because cancellation. | New implementation with ERFC.Issue 69069 , Issue 97091 | integrated in OOo3.2 | |||

LEGACY.NORMSDIST | "This is exactly NORMDIST(x)." Should be "This is exactly NORMDIST(x;0;1)." because mean parameter and standard deviation parameter are not optional. | correct in draft 22a of ODFF | |||

Parameter 'C' is required. 'C'=0 is density function, all others are cumulative | change in calc Issue 96837 | integrated in OOo3.1 | |

QUARTILE | Example calculates with Quart=1.5 although there is a constraint INT(Quart)=Quart |

SKEWP | not yet implemented | ||||

STDEVA | The text "cells with text are converted to 0;" conflicts with "The handling of strings is implementation defined." | Mail to OASIS [4] | |||

TDIST | In Draft 26 it was corrected to show the cumulative function. In addition it was renamed to LEGACY.TDIST to be consistent with other right tailed distributions. | Calc (and Excel) evaluates the cumulative function. | Implementation has to be adapted. | not started | |

TREND | The optional parameters knownX and newX may be empty, denoted as ;; |
knownX and knownY cannot be empty |
|||

Parameter AllowOffset is Logical |
Parameter is 0 or not 0 |
