Rounding or no rounding?

-- Rounding
Select CAST(Number as numeric(9,2)) From Table

-- No rounding (probably a better way to pull this off)
SELECT CAST(FLOOR(number * 100) / 100 as decimal(9,2)) From Table

Jim, just curious, why do you cast the field rather than just using ROUND or FLOOR directly?

Round does the rounding, but doesn't change the data type, so rounding to two decimal places returns 12.4700000.  A fun nugget of info I learned the last time I sat for the 70-433 SQL 2008 Development exam.
Declare @number decimal(19,9) = 12.4653453544
Select CAST(@number as numeric(9,2))
SELECT ROUND(@number, 2)
