title: Rails: How to print a decimal as a percent?
body: <p>Is there a way to print a decimal as a percentage, so only the two digits after the period? </p>
  
  <p>My decimals will always be between 1 and 0, so I suppose it would work to call <code>number.round(2)</code> starting with the third character, but I can't find the syntax for that anywhere. </p>
  
  <p>To clarify, I want the number to be stored as a <em>full decimal</em>, but printed as a <em>percentage</em>.</p>
