My biggest concern is the conversion to FLOAT to do the sum. FLOAT only has a precision of 15 significant digits. If you go any higher than that, you will start to get siginficant rounding errors without any warning.

Use the appropriate datatype for these types of things. For most sums, FLOAT isn't it.

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.
