Good: different currencies have their share.
Improvable: Different currencies have different "spacing conventions" which are not allowed for in this module.

For example, in Germany, Austria and France, numbers are widely written like this:
123.456,78
(comma and dot "switched")
In Switzerland, both comma and dot may be used as decimal markers, whereas an apostrophe serves as a separator in large numbers:
123'456.78

Anybody, too, think that it would be helpful to have either a dropdown to choose the number style from or input fields to configure 2 individual separators?
