Decimal Places In Node_Description??

There's been several good posts on using the node description of a model as the end user description for a specific cluster. My model uses a number of continuous input columns defined as currency from a fact table in the source cube. After processing, the node description has elements that look like this:







-0.5799759795 <=Interest Expense <=0.8397462488 ,

Since the source data is currency, this makes the node description look a little strange. The data type in the model is set as double. The precision implied by the description is not what I want the model to consider. In the case above, the difference between the numbers listed is not significant.

It would be great to have a better node desciption that doesn't imply so much precision, but the bigger question is why does the cluster model turn currency types into doubles. Should I set the data type to long in the model so that cents are ignored? I know I should probably use discrete inputs, but I don't want to have to discretize the currency values in the cube since this would require me to set up fact dimensions for each currency column in the fact table.
