#16688 — function argument type

hi to all
I'm trying to call an applet method from a js script

this is the code

function jump() {
  var x = 1374795;
  var y = 5700582;
  var z = 170;
  document.xnavigator.jumpToCoordinate(x,y,z);
}

the problem is that it works only on some browsers (firefox on Linux)
In other browsers the applet throws an illegalarguments exception, but this version works

function jump() {
  var x = 1374795.001;
  var y = 5700582.001;
  var z = 170.001;
  document.xnavigator.jumpToCoordinate(x,y,z);
}


Have you ever had an issue like this? Is there a workaround?
How can I get control about variable's type?

Thank you

Does the second format work in firefox on linux?

It looks like it may be a problem in the way ints and floats are handled 
by or handed to the applet.

If the second format works in all browsers, it may even work as:

function jump() {
  var x = 1374795.0;
  var y = 5700582.0;
  var z = 170.0;
  document.xnavigator.jumpToCoordinate(x,y,z);
}

in which case obviously the applet is loking for a float, not an "int or 
float", and appending .0 to an int is often sufficient to force the 
underlying code to treat it as a float (in many cases just appending "." 
is sufficient).

js wise, the code you have looks fine, there are no 'syntactical' errors from the js standpoint.
Bear in mind that js will use whatever object/method is exposed from an embedded element, so long it's given access.  Now, your error doesn't seem to be a js one, so much as a Java one, whatever the exposed method is needing as argument, you'll have to check the Java Script itself, or its documentation if any provided.
