     * is:<pre>
     *      prefix + longitude + separator + latitude + postfix
     * </pre>
     * The prefix, number of significant digits of the longitude and latitude,
     * the separator, and the postfix can all be changed, but sometimes
     * it is desirable to change the format.

     * the format in which the geographic coordinates are displayed.
