title: JUnit assertions : make the assertion between floats
body: <p>I need to compare two values : one a string and the other is float
  so I convert the string to float then try to call <code>assertEquals(val1,val2)</code> but this is not authorized , I guess that the <code>assertEquals</code> doesn't accept float as arguments.</p>
  
  <p>What is the solution for me in this case ?</p>
