Comment 3 Winfried Donkers 2016-07-07 07:38:22 UTC
AMORLINC and AMORDEGR are Add-in functions from the Excel Analysis pack and as such primarily complies with Excel.
Therefore these functions return an error with basis 2. There is no technical/numerical need in the functions to reject basis 2; the functions work fine with this constraint removed.

There are several 'solutions':
1-leave all as is, i.e. accept that the functions do not fully comply with ODFF1.2 - but do change the help text;
2- make the functions compliant with ODFF1.2 and accept breaking the inter-operability with Excel - and add a note to the help text;
3- rename the functions to AMORLINC_ADD and AMORDEGR_ADD and add new ODFF1.2-compliant functions AMORLINC and AMORDEGR.

1 and 2 are not full solutions, so I tend to opt for 3.

@Eike: Given your expertise of both Calc and ODFF, what do you advise?
Comment 4 Eike Rathke 2016-07-12 16:31:25 UTC
I'd rather accept argument value 2 as basis and mention in the help text that Excel doesn't support it. Gnumeric fwiw also accepts it.
Comment 5 Winfried Donkers 2016-09-22 15:02:58 UTC
I'll make Calc accept basis 2.

Changing the help text as suggested in comment 4 is beyond my capabilities.
@Raal: perhaps you could create a separate bug report to address the change of the help text?
