The pages on this site contain documentation for very old MS-DOS software, purely for historical purposes. If you're looking for up-to-date documentation, particularly for programming, you should not rely on the information found here, as it will be woefully out of date.

'This example uses the CCUR function to convert a double-precision,
'floating-point value to currency data type. The program performs an
'interest calculation in double precision, but displays the result as
'a currency value. The SetFormatCC routine is used with the FormatC$
'function to display the currency amount in the formats of the United
'States and West Germany.
 
'Note: To run this example you must use a Quick library that includes the
'procedures contained in the date/time/format library files. The following
'include file must also be present.
