Different Culture number format using a website

Question

Hi,
My web application has to support different cultures for displaying the price values.
For example,
if german user is using application then price value has to be displayed like 1,05 [decimal separater is comma, thousand separater is dot]
if chines user is using application then price value has to be displayed like 1.05 [decimal separater is dot, thousand separater is comma]
I will call the application[set language German] from my browser  after configuring the application.This language has been set my application whereever i calling the application. So other language is not working to display the price value.
Note:
Is there any default language setting in IIS if access the first time?
or
For accessing database, i am using BORLAND.DATA.ADODBXCLIENT.dll to access the interbase database in my web application. Is it any default language setting when access the database? I saw the log, if set de-DE when access first time then the price has been logged like 1,05. When i change the my language for en-EN in my browser then the price has been logged like 105.
