มอดูล:Coordinates

--
This module is intended to replace the functionality of  and related
templates.  It provides several methods, including
: General function formatting and displaying
coordinate values.
: Simple function for converting decimal
degree values to DMS format.
: Simple function for converting DMS format
to decimal degree format.
: Export the link used to reach the tools

Determine the required CSS class to display coordinates
Usually geo-nondefault is hidden by CSS, unless a user has overridden this for himself
default is the mode as specificied by the user when calling the  template
mode is the display mode (dec or dms) that we will need to determine the css class for
local function displayDefault(default, mode)
	if default == "" then
		default = "dec"

	if default == mode then
		return "geo-default"

		return "geo-nondefault"

Check the input arguments for coord to determine the kind of data being provided
and then make the necessary processing.

link
Simple function to export the coordinates link for other uses.
Usage:
	 link 
function coordinates.link(frame)
	return coord_link;
end
--
dec2dms
Wrapper to allow templates to call dec2dms directly.
Usage:
	
decimal_coordinate is converted to DMS format.  If positive, the positive_suffix
is appended (typical N or E), if negative, the negative suffix is appended.  The
specified precision is one of 'D', 'DM', or 'DMS' to specify the level of detail
to use.
coordinates.dec2dms = makeInvokeFunc('_dec2dms')
function coordinates._dec2dms(args)
	local coordinate = args1
	local firstPostfix = args2 or 
	local secondPostfix = args3 or 
	local precision = args4 or 
	return convert_dec2dms(coordinate, firstPostfix, secondPostfix, precision)
end

format depending on the precision of the decimal input.
