An excellent module! Simple and yet flexible interface to use. At our business function, we have to be able to serve our international customers in different currency formats based on their geographical locations. The module fills out this requirement very nicely for on the server side.
The previous comment assumed that numerical formatting took place on the local machines and so locale settings would prevail. However, our Asian customers are served from servers in San Francisco and European customers from those in New York, which can display proper currency formats based on their account settings. This module does this job splendidly! Nice work!
