P5.Math.js

Javascript implementation of the following Processing convenience methods declared in http://www.google.com/codesearch/p?hl=en#Ej56LtI_pY0/trunk/processing/core/methods/demo/PApplet.java

p5.sq()<br /> p5.constrain()<br /> p5.degrees()<br /> p5.mag()<br /> p5.dist()<br /> p5.lerp()<br /> p5.norm()<br /> p5.map()<br />

Very small in size, probably better to copy the minified version into your project, rather than linking to it.

Added optional extensions to the main Math object:

Math.sq()<br /> Math.constrain()<br /> Math.degrees()<br /> Math.mag()<br /> Math.dist()<br /> Math.lerp()<br /> Math.norm()<br /> Math.map()<br />

This code is not checking whether the methods already exist, use it at your own peril.

Note: Math does not get constructed and instantiated, but rather initialized. Adding methods with Math.prototype.myMethod does not work, rather use Math.myMethod
