Discount percentages and comma's

[nilsenpaul]

Description

Our editors use comma's as a decimal separator. That works fine, except when they try to add a discount with decimals. Then 7,5% becomes 7% after saving. If you use a dot as the decimal separator, the correct discount percentage gets saved. However, if you re-open that discount, the field says 7,50%. Saving that sets the percentage back to 7%.

Steps to reproduce

1. Use a language with commas as decimal separator (Dutch, in our case)
2. Whilst using Dutch, try to navigate to discounts and create a new one
3. Use 7,5% as the discount percentage and save
4. Reopen that discount. Percentage is now 7%.
