Examine Changes in Functions for ODFv1.2
This is a collection of the differences I found and what I know is already done or in progress. I also note, when I found problems in the draft spec itself. You are invited to add your observations. Regina 19:40, 10 October 2008 (CEST)
Function | ODFv1.2 | CALC | Action | Progress | |
---|---|---|---|---|---|
BETADIST | Draft Spec misses faktor 1/(b-a) in densitiy case | not yet implemented | Inform Eike Rathke | Done 2008-06-07 | |
Has density case and optional parameter, to choose between density and cumulative | not yet implemented | expand function to density case and additional parameter | tracked in Issue 91547 , function code is ready, finishing implementation depends on Issue 91602 | ||
BINOMDIST | Parameter C is integer with constraint to 0 and 1. It should be Logical than in other distributions | C=0 is density, all other values of C are treated as cumulative | - | - | |
LEGACY.CHIDIST | Returns 1 for x <0 | x < 0 returns Err:502 | expand domain to x < 0 internal | patch in Issue 94555 | |
CHISQDIST | density function and cumulative left tail of chi-square distribution | not yet implemented | prepare Implementation | patch in Issue 94555 | |
CHISQINV | inverse of CHISQDIST(...TRUE()) | not yet implemented | prepare Implementation | patch in Issue 94555 | |
EXPONDIST | Parameter Cumulative has type Logical and is optional. | Last Parameter C has type Number and is not optional. C=0 returns denisity, other values for C return cumulative function. | - | - | |
FDIST | density function and cumulative left tail of F-distribution | not yet implemented | prepare for implementation | first draft, depends on BETADIST Issue 91547 | |
Name conflicts with actual FDIST, which calculates right tail. | get new UI-name | have brought problem to dev@sc | |||
FINV | inverse of new FDIST | not yet implemented | - | - | |
Name conflicts with actual FINV, which calculates inverse for right tail. | get new UI-name | - | |||
GAMMA | Parameter is constraint to >= 0 | Gamma is definied for all real numbers, but non-positive integers | Inform Eike Rathke | - | |
not yet implemented | prepare implementation using full domain. Add UI texts. | path in Issue 94555 | |||
GAMMADIST | Last Parameter has type Logical | Last Parameter has type Number | Change type internal to bool. Change UI texts. | patch in Issue 94555 | |
Domain for Parameter x includes x < 0 | x < 0 returns Err:502 in OOo2.* | Change implementation | integrated in OOo3.0 | ||
TDIST | Draft spec shows the density function. | Calc (and Excel) evaluates the cumulative function. | Inform Eike Rathke | Done 2008-10-09 | |
Functionname | ODF | Calc | Action | Progress |
