title: Which method will be better when multiply 100 with BigDecimal?
body: <p>Here I have a question when using Java BigDecimal.
  Which way will be better when I want to multiply 100 for a object of BigDecimal.</p>
  
  <ol>
  <li>multiply 10 twice;</li>
  <li>movePointRight(2);</li>
  <li>scaleByPowerOfTen(2);</li>
  <li>any other way? please show me if there is.</li>
  </ol>
  
  <p>BTW, it will be used for commercial calculation, so I'm considering the precision rather than the speed. </p>
