A number of functions, including PRICEDISC use GetDiffDate() to calculate the
result.
GetDiffDate() doesn't implement basis 0 (NASD) correctly - it makes no attempt
to change month end dates.
Example:
PRICEDISC(2009-07-31;2009-08-5;2%;100;0) returns
99.9778 based on 30+5-31 = 4 days difference in dates (!)
Excel correctly returns
99.9722 (5 days difference in dates)
(note that the inverse function YIELDDISC uses a difference routine (!) -
YEARFRAC - I have not investigated that yet)
Reference: NASD implementation was also the subject of issue 84934 - for
DAYS360.
PS: GetDiffDate() also gives the days in the *first year* - this is often not
what is required, and is different from Excel. I'm not yet sure how this should
be specified.
I guess there are ODFF implications here?
