Answer 1

Why are you using FLOAT? I find that in a lot of cases people use FLOAT when they don’t understand its limitations or peculiarities. For storing decimal values with 2 decimal places, I would use decimal instead.

CREATE TABLE #floob(f FLOAT, d DECIMAL(10,2));

INSERT #floob SELECT 2.02, 2.02;
INSERT #floob SELECT 2.7, 2.7;
INSERT #floob SELECT 1.5, 1.5;

SELECT f, f_as_d = CONVERT(DECIMAL(10,2), f), d FROM #floob;

Results:

f        f_as_d   d
------   ------   ------
2.02     2.02     2.02
2.7      2.70     2.70
1.5      1.50     1.50
