Number and Number Formatting [get from ColdFusion value="0E-18"="0.000000000000000000"]

1. Flex application get from ColdFusion next value = "0E-18".

2. ColdFusion get from MSSQL decimal value = "0.000000000000000000".  (decimal precision are 18)

Issue/Bug:

1. How I can show "$0", that mean currency + "0".
2. Now flex application show the value = "-$18".

Can you suggest me some solutions?
