I guess the real key here is that if you're dividing by zero, there's something wrong with your data, your code, or both. I've never ignored divide by zero errors and probably never will. 😉

RBAR is pronounced "ree-bar" and is a "Modenism" for Row-By-Agonizing-Row.
First step towards the paradigm shift of writing Set Based code:
________Stop thinking about what you want to do to a ROW... think, instead, of what you want to do to a COLUMN.

Change is inevitable... Change for the better is not.
