Maybe related to #1696

I think is is either related to the usage of the "." in a culture with the "," for decimal or maybe linked to a three decimals number.

I may try to fix it if you want.

well well well

8.33 is working.

It may be linked to the format_money function.

Excessively precise monetary amounts aren't allowed.

What needs to be done to close this issue is to improve the error message.
