Functions

calcM	`open static fun calcM(lat: Double): Double`
calcRho	`open static fun calcRho(sin2Lat: Double): Double`
calcV	`open static fun calcV(sin2Lat: Double): Double`
computeLatLon	Computes Latitude and Longitude based on an SVY21 coordinate. This method returns an immutable LatLonCoordiante object that contains two fields, latitude, accessible with .getLatitude(), and longitude, accessible with .getLongitude(). `open static fun computeLatLon(N: Double, E: Double): LatLonCoordinate!` Computes Latitude and Longitude based on an SVY21 coordinate. This method returns an immutable LatLonCoordiante object that contains two fields, latitude, accessible with .getLatitude(), and longitude, accessible with .getLongitude(). This method is a shorthand for the functionally identical public LatLonCoordinate computeLatLon(double N, double E). `open static fun computeLatLon(coord: SVY21Coordinate!): LatLonCoordinate!`
computeSVY21	Computes SVY21 Northing and Easting based on a Latitude and Longitude coordinate. This method returns an immutable SVY21Coordinate object that contains two fields, northing, accessible with .getNorthing(), and easting, accessible with .getEasting(). `open static fun computeSVY21(lat: Double, lon: Double): SVY21Coordinate!` Computes SVY21 Northing and Easting based on a Latitude and Longitude coordinate. This method returns an immutable SVY21Coordinate object that contains two fields, northing, accessible with .getNorthing(), and easting, accessible with .getEasting(). This method is a shorthand for the functionally identical public SVY21Coordinate computeSVY21(double lat, double lon). `open static fun computeSVY21(coord: LatLonCoordinate!): SVY21Coordinate!`
