Price using comma and the weight and height use dots

[escozul]

This works fine for the price, but how bout the rest of the items?
I have to hack into the database to reduce the number of decimals for the weight and height, but what about the decimal point and thousands separator? I need to have a comma as a decimal point and a dot as a thousands separator for the weight and height variables. Its a but strange to have the price using comma and the weight and height use dots!

Could you guide me please?
