For years I have put up with the 2 decimal places that ArcGIS adds to the "currency" formatting, but most of the time I do not want them and end up removing them in my exported map images. I cannot see a way to edit the number of decimals - does anyone have any ideas how to get rid of these decimals?
EDIT: There may be some business reason you need to have the field set to currency but I think I would manage it in a different way.
Since it say localized currency settings
you might try looking at the windows settings for your computer.
OLD: If you open the attribute table.
You could use Brad's answer in conjunction with a label expression that adds the dollar sign (or other appropriate currency symbol).
