Dollar sign ($) in text box format rounds decimals?

I searched for awhile and could not find a similar post. I'm trying to add a dollar sign to the total amount of an invoice. In the source expression I have:

TempSalesInvoiceLine."Amount Including VAT"

and the amount appears correctly as "92.20". However, when I add:

'$' + FORMAT(TempSalesInvoiceLine."Amount Including VAT")

It displays "92.2". It is also making the value show up with Left horizontal orientation, despite being set at Right. When I add the '<Precision,2:2><Standard Format,0>' before the source information it gives me an Overflow error on the 92.2 value. I could work around it by putting a '$' label in front of the textbox, but I would like something cleaner if possible.
