title: Issue with rounding number in robotframework
body: <p>I have problem with rounding number with 500. I am giving my example below and want to see how i can resolve this problem.</p>
  
  <p>example:
  Here i am calculating based on values from application: </p>
  
  <p>{expectedResults} = 2242.31
  {income} = 7166.67</p>
  
  <p>${expectedResults}=    Evaluate    (${expectedResults} / ${income})*100
  ${expectedResults}=    Convert To Number    ${expectedResults}    2</p>
  
  <p>my results would be like :31.29%</p>
  
  <p>but if i get results like 30.0001 then i am getting my value as 30.0 instead of 30.00. I wanted to get the value as 30.00 but not able to find solution. Can any one give me the solution to this problem? Thank you in advance.</p>
