This template converts a positive decimal degree value to degrees° minutes' seconds'' format or to degrees° minutesmsecondss format (the degree symbol ° is invariant between the two formats).
Parameter p is optional and defaults to 3. It is the number of decimal digits that the seconds are rounded to.
Parameter sup is optional and changes the default apostrophe-format for arcminutes and arcseconds (1° 2′ 3″) to the m-s-format for arcminutes and arcseconds (1° 2m 3s). Any non-blank value has this effect, but using |sup=ms is customary.
