You can add in the field a maximum of 12 characters.
You can add numbers (0 to 9), commas or dot (commas are for thousand and million separator and the dot is used as decimal separator).
You can have or not thousand and million separators.
Thousand and million separator have to be used in the same time, if it is the case. (you cannot use in a million number just thousand separator e.g. 1256,678.34 will considered invalid)
The price can have maximum 2 decimals.(if there are more the number will be considered invalid; eg 1,345.342 will be considered invalid))
If there is no value after the decimal separator the separator will be eliminated ( eg. 345,234. will be considered as 345,234)
