Rounding not working

[Faye]

When I

SELECT CAST(96.58 AS DECIMAL(10 , 0)), it returns 97.

When I

SELECT CAST(575629 / 54 AS DECIMAL(10 , 0)), why it returns 10659? It
should return 10660, right?

What am I missing?

Thanks,

Running this will explain it:

SELECT 575629 / 54

When integer dividend is divided by an integer divisor the result is an
integer that has any fractional part of the result truncated, so you get
10659.

But try this:
SELECT CAST(575629 / 54.0 AS DECIMAL(10 , 0))

or

SELECT CAST(1.0 * 575629 / 54 AS DECIMAL(10 , 0))

Those will give you the expected result 10660, because the higher precedence
argument data type is the resulting data type of the division.
