# Prime Number Calculator

This is a very simple prime-number calculator, based on a Java
applet. "View Source" to see how HTML and JavaScript interact with
the Java applet. (The Java source code is available here; the HTML/JavaScript source here.) The primary purpose of this
calculator is an example of what Netscape calls "LiveConnect"
(Java/JavaScript/HTML interaction; it's also supported in Microsoft
Internet Explorer), to accompany a forthcoming article on JavaScript
by Andrew Schulman, for Web Review.
The x and y values can be full JavaScript expressions, such as
Math.pow(2,31)-1 to verify that Mersenne(31) is prime, or
Math.pow(2,47)-1 to see the factors of Mersenne(47).
