  <p>the author uses parseFloat with a second argument, which I read here:</p>

  <p>Is supposed to specify the base of the supplied number-as-string, so that you can feed it '0x10' and have it recognized as HEX by putting 16 as the second argument. </p>
  
  <p>The thing is, no browser I've tested seems to do this.</p>
  
  <p>Are these guys getting confused with Java?</p>
