Using comma in measurements

Hi! I can't seem to find a solution elsewhere, so I turn to you now in hope of help!

I have a textbox where the user should fill in an measurement in meters, but I would like the box to accept the swedish kind of punctation with comma (for example 1,5 meters) instead of using full stop (1.5 meters). Is there a way of doing this?

Thanks in advance!

It's not already possible ? Do you get an error when you do that ?

I dont get an error, but it rounds off the number, so 1,5 turns to 1.

You mean on the products edition page of the back end ?

Ohh.. it was just me being dumb, I solved it now! Duh. Thanks for the help anyway!
