Hello,
my question belongs to worksheet-functions beginning with coup, for example
coupncd or couppcd and so on.
Is there any hint, how these functions calculate the result?
In some of the helpfiles you can find the math formula, the calculation is
based on.
For these coup*-functions I cannot find such hint.
I would like to know, which math formula is behind
coupncd
couppcd
coupdaysnc
coupdaybs
Has somebody further knowledge about the internal calculation?

Kind regards
Volker
