Currency Modules

Introduction

This module type adds formatting to a decimal number that is passed to it. The module takes the decimal number and formats it into the proper currency layout.

In addition to simple formatting, a currency module could convert values of various currencies. It could display US currency, Eurodollars, or Canadian currency using the daily rate of exchange data to give updated values from day to day.

The currency module could go one step further and do a lookup every hour to update the currency values.

Module type: CURRENCY
