SQL query to store float values in french culture.

Here is how my requirement goes..

I have an application where users can store float values into the SQL server. Here float values are period(.) based. I have now started supporting the users who use the french culture where the float values are Comma(,) based. Example: 13.75 is represented as 13,75. Instead of making changes to my code i.e the way i am inserting/retrieving the date now, is there a way i can handle this requirement based on culture. Like, if I specify the culture, will I be able to insert float inputs as comma(,) based values without disturbing my existing code?

Any help is appreciated

Thanks,

Chandrahas.
