If you use the floating currency character only once, it inserts
    the dollar sign ($) in the next character position in the edited
    value.

    If you supply the floating currency character more than once at
    the beginning of an edit string, it suppresses leading zeros.
    To suppress up to four leading zeros, supply the character four
    times at the beginning of the edit string.

    The floating currency character inserts the currency sign to the
    left of the first printed digit of the edited value.
