MathGlobalizr

A function to get rid of the stupid "Math" object once and for all!

It allows this sort of syntax:

 myVariable = floor(myVariable)
 myOtherVariable = random()

The cleanest, easiest dom api ever! It will change your life!

I always thought there was a better way to access the dom. This is a tool that allows you to use extremely simple syntax to access dom elements. It makes an object with the name of your choice (I chose "$") that contains a reference to all elements that have an id.

example:

<script> $.foo.innerHTML = "Hello world" </script>

You can even choose to use an object that already exists (I chose "document" because it makes sense)
