var normalizedVal = esri.geometry.xyToLngLat(42215329, 1321748);
console.log(normalizedVal); //returns 19.226, 11.789
var value = esri.geometry.xyToLngLat(42215329, 1321748, true);
console.log(value); // returns 379.22, 11.78
But the part for esri.geometry.xyToLngLat(long, lat) has no examples
Am I just confused? All I am trying to do is use these to go from UK WKID (27700) to google map friendly co-ordinates (I realise there may be a small error, but all I need is a good approximation)
Those methods are only for converting from Web Mercator to Geographic and the reverse. If you want to convert to another coordinate system take a look at the Geometry Service's project method:
Thanks for that - I realize I probably need the projecyt method - however what the post was really about was the mis-match between thing and the snippet the (it is under the esri.geometry.lngLatToXY but the snippet is for XYTolngLat.
