CompareTo on primatives

[GoogleCodeExporter]

Is it possible to support CompareTo() on doubles and ints?

Using C# such as

  new jQuery(HtmlContext.document.body).append("Hello world<br/>");

  var first = 3.223;
  var second = 5.233;

  var res = first.CompareTo(second);

  new jQuery(HtmlContext.document.body).append("Result: " + res);

generates an invalid call.

  var first = 3.223;
  var second = 5.233;
  var res = first.CompareTo$$Double(second);

This then fails at runtime. Substituting in prefix comparison functions is an 
option but it would be nice to have support for the standard functions in CLR 
mode. Generating prefix form JavaScript would be fine.

Why not simply implement:
Number.prototype.CompareTo$$Double = function(second){
}

?

That's just what I did. :-)

The issue can be closed now.

Cool, does this code exist in JsClr?

Yes, you applied the patch. The below test cases work which is enough to be 
useful:

double x = 7.445;
double y = 7.332;
new jQuery(HtmlContext.document.body).append("x.CompareTo(y) = " + 
x.CompareTo(y) + "<br/>");
new jQuery(HtmlContext.document.body).append("y.CompareTo(x) = " + 
y.CompareTo(x) + "<br/>");
new jQuery(HtmlContext.document.body).append("x.CompareTo(x) = " + 
x.CompareTo(x) + "<br/>");
int i = 4;
int j = 5;
new jQuery(HtmlContext.document.body).append("i.CompareTo(j) = " + 
i.CompareTo(j) + "<br/>");
new jQuery(HtmlContext.document.body).append("j.CompareTo(i) = " + 
j.CompareTo(i) + "<br/>");
new jQuery(HtmlContext.document.body).append("i.CompareTo(i) = " + 
i.CompareTo(i) + "<br/>");

x.CompareTo(y) = 1
y.CompareTo(x) = -1
x.CompareTo(x) = 0
i.CompareTo(j) = -1
j.CompareTo(i) = 1
i.CompareTo(i) = 0

I didn't check it with NaN etc
