I find that I need to use several different rounding styles in the same design. I set the one I use most often as the default, then specify it directly in the "resize" command. Note that all of the functions in the fixed point package expand the number, and thus do no rounding. > The current enumeration handles two of the eight possibilities.

Options were made in the original packages to allow for more rounding modes. -- This message has been scanned for viruses and dangerous content by MailScanner, and is believed to be clean.Received on Mon May 20 07:16:45 2013
