Taking out unwanted 0's

We have using a Narative view for on of our reports.  The view referencing a number and currency column.  When either the number or currency column is blank a 0.00 appears in the report. 

In the number column, we created a statement of 'CASE WHEN CAST(number as char) = 0 THEN ' ' ELSE CAST(Number as Char) END'.  The statement works for the number column.  We need the currency column to be in a normal us dollar format ($1.00), but using the same logic above takes away the dollar format. 

Any ideas on how to make this work?

Thanks.
