title: Expressing number in exponential format
body: <p>We are working on a flex project</p>
  
  <p>I need to display a number coming from a calculation in exponential format- essentially, show 80900 as 8.09* 10^4; 4.1e-4 as 4.1*10^-4 etc</p>
  
  <p>Any simple way by which I can take the number and separate the exponent and the significand- without getting into string operations.</p>
