Hi,

I'm wondering what the actual mechanics are for the COUPPCD and COUPNCD Excel functions are - as in the behind the scenes calculations both of these functions execute before arriving at a solution? As I'm looking to use a modified version of both COUPPD ad COUPNCD functions for some calculations and so I'd like to understand how these functions behave so I know how to alter them for my own use.

Also is there a database or online link that explains the mechanics of these (and other) Excel functions that someone could please provide me with?

Thanks
