thanks for the looks and comments. for the few of us pinheads that are after certain excel functions to catalyze higher order math functionality within the VB environment, it really could not be much easier:

...where XXXXXX() is one of the "sanctioned" functions for VB
The list of all accessible/callable functions may be found at:

Callable Excel Functions thanks, again, for the effort...
