Numeric Output format Excel issue

Hi there,

I've made a .rtf report  but i have the following problem:

In the database the field is a number (20,4) but excel sets the decimal values only to two. (the column on excel output is set as general)

Example:

database                             excel

10,0000                                  10

10,0200                                  10,02

10,0030                                  10,00

10,0050                                  10,01

10,0005                                  10,00 

It not eliminates the rest of decimal values, it only hides them and i have to click in the increase decimal button in order to show - in excel.

I do not want this field to be text because is a mandatory requirement from the client in order to make filters and ordering ans sum column values,etc
