Why can't I get a response to my question about Marketpress??

I initially posted my thread here on how to list a product's cost in Cube points, and not dollars. It was then moved to the suggestion forum where it now remains.


However nobody bothers to answer my question there, so here it is again. Until you add this option I want to add it myself. Please provide an answer to the following question. Thanks in advance.

How can I create a custom currency called Cube Points?

I can see where I need to add a new currency to the array which I found in marketpress-data.php

But I'm unclear what these numeric values represent. This for example is the Brazilian entry.
"BRL"=> array("Brazil, Reais", "52, 24"),

Some entries have 1 number, some have two, and some even have 3 or 4.
