Datediff -Year and Rounding

Hi, I have a statement similar to this...
SELECT
DATEDIFF(year, acc.acct_anuit_birth_dt, GETDATE()) AS 'age'
FROM rpsacct_t acc
The acc.acct_anuit_birth_dt field is a date field. The statement returns
whole numbers based like 64 etc... What I would like it to do is to return
the age to two decimal places eg... if someone is 64 years and 6 months, I'd
like to get back 64.50 Any idea how I might do this ?
ThanksTry this:
SELECT
DATEDIFF(month, acc.acct_anuit_birth_dt, GETDATE())/12. AS age
FROM rpsacct_t acc
If this is not what you want, post more sample data and expected
results.
