Rounding a result

When using the PMT function to calculate a loan payment, the result I'm getting is a negative number with more than 2 decimal places.

-327.4347167 I am then taking the result, (which I have set to only 2 decimal places)
-327.43 and multiplying it by the numer of payments to calculate the total of 60 payments.
I'm getting -19,646.08 and it should be -19,645.80 This result I'm getting seems to be using is using those numbers that should have been rounded off.

How do I round off the result to a number with 2 decimal places and use only the rounded number to perform other calculations?

This is my example:
Interest_Rate - 3.05
Loan_months - 60
Loan_Amount - 18,200.00


Here's my formula to calculate the payment:
=PMT(Interest_Rate/12,Loan_Years,(Loan_Amount))

Here's my formula to calculate the total of payments:
=-Loan_Months*Scheduled_Monthly_Payment

Hi
you probably have only changed the format (the display).
To really round use
=ROUND(your_formula,2)
