Problem with Crystal report

Hai to all,
I am using crystal report 9 for reporting and ASP as my front end.

I am having problem in decimal fields. In format tab I have changed the number format to 1234. But in the report it shows the result as 1234.00

Please say me what might be the problem, and how to solve it

Try
Click right buttonover field
Select Format Field
Select Number tab
Click over Customize button
Set number to No Decimals in Decimals combo box

I think u didnt read my question well. I have specified that I have tried this option but there is no result.

Thats Ok, I got the solution. I have created the formula field and applied the format option to formula field. now I have the result with no decimals.
