Want only 2 digits

Wanted to know if there is any mathematical function which can return just first two digits of a numeric value without rounding it.

I have used to Round function but it rounds it, want some other function which does not do that.

select round('3045.4556',2)

Output
------
3045.46

I want output as 3045.45

DECLARE @Test DECIMAL(8,4)
SET @Test = 3045.4556

SELECT LEFT(@Test,2)

Note that if the value is negative, it returns the "-" character and the first digit.

For values between 0 and 10, it returns the first digit and the "." character.
