}
}
function showPosition(position) {

If the aim is to format the number as a string with a given precision then use the toFixed function, e.g.
var numberOfDecimals = 4;
var latitude = position.coords.latitude.toFixed(numberOfDecimals);
var longitude = position.coords.longitude.toFixed(numberOfDecimals);
If the intention is to limit the precision of the original number, then the rounding might be used:
var rounded = Math.round(value * 10000) / 10000; // leaves only 4 digits
