How to display Currency or Money in UDF

Hi,

I have created a UDF in RDR1 ( Sales Order Lines Table). The field type is price, i want to display the price with currency or money. for example if user enters 12.00 in that field then it should be displayed as USD 12.00 or $ 12.00

is there any way to do this? Thanks in advance.
