title: javascript fraction to percent
body: <p>When I tried to convert fraction in Javascript, I am facing a problem. 
  I need to make a fraction value to percent value. 
                             a = 0.0175
  It should be displayed as 1.75%.  I tried to multiply by 100. But I am getting some extra fractions added to  the right - 1.7500000000000002 . I just need 1.75, not any more zeroes added to the end.</p>
  
  <p>Thanks in advance.</p>
